the electrons must be traumatized after bumping into all of those photons

What I like about this channel is that he is quite frugal when it comes to explaining complex things. The low production budget makes it more interesting.

Note when he means extra protons, he means that electrons had left the surface.

Being a JEE Aspirant, I learnt this recently but never knew how exactly it worked.

Its impossible to say anything bad about this guy. Hes just so smart and wholesome

That´s exactly how a laser printer works: A drum is negatively charged, then a laser (or a LED bar) kicks out electrons off this drum corresponding to the printing pattern, toner is beeing released and attracted by the charge, forming a physical image on the drum, then the toner is rolled out onto the positively charged paper and finally cooked in with heat by another drum. The hairy wires at the printer´s ass discharge the paper to ground, so it won´t get sticky. That easy :)

I like how you don't spoon feed us with animations. You actually give us a demonstration. Thank you for putting so much of effort into what you do ❤️

I've only recently discovered your videos. Great stuff! Now I'm going to have to look through you're previous videos to see what I've been missing! Keep up the good work. Much appreciated!

I really like how he explains these super complex phenomenons in a way that simplifies it down to easy-to-understand terms. The practical way of showing it definitely helps as well.

This guy teaches more physics than schools

Wow! I've watched literally dozens of KZfaq videos, TV documentaries and read multiple articles trying to get my head around the "wave-particle duality of light" thing and, even though I know that wasn't the central theme of this video, at the end you nailed it better than any presentation of it I've seen before. The key was differentiating the high frequency vs the lower frequency of the EMS in terms of particle & wave tendencies. Seriously insightful & helpful.

I'd like to give Thanks to James for showing us educational videos with layman's terms. I've always been interested in science but never to a course in school. As a 33 year old man still learning things new everyday , they are quick and simple and easy to understand. Thank you so much for your time and effort James ! You da Man!

The positive charges are electron "holes" instead of protons. The protons are always in the core and do not move. So touching the plate with the positively charged rod actually drains the electrons from the plate to balance out the charges, leaving a net + charge on the plate.

Great practical explanation of the "quantum bounce" Remember always wear eye and skin protection if your in the same room with a functional UV-C light source.

This is the best video on the internet regarding the relationship between the photoelectric effect and positive/negative charge. Thank you. I learned something.

thanks a lot i was so frustrated at this since months, this is a topic of chemistry in my syllabus and no teacher was actually going into the details and so even sometimes in the live demonstrations i barely get anything but i am just so happy for the first time i got something thank u!

I love Him.., he's the Best Chemistry and Physics Teacher Anyone Can Have...😃

This fractured my brain. And I have no regrets. Lol. Especially at the end where he answered a question I pondered for so long without finding a way to articulate it, regarding radio waves and ultraviolet particles. Of course this is generating a flurry of new questions. 🤔🤔

That was the first time, in all the years I've been into this that a particle was explained this way. GREAT JOB! 👍👍

Oh wow, what an amazing physics experiment demonstration! I was looking for something like this for ages!

This is a science fair winner if I ever saw one.

Fantastic presentation! This is the first experiment I've seen showing how you can differentiate between positive and electric charge buildup and makes the connection about how they must have determined what interacts with it (light), besides other charge.

Incredible demonstration! I’ve never been able to visualise the photoelectric effect so well. Thank you

this is the coolest experiment I have seen in, probably my whole life.

In case you ever wondered, this is in a nutshell how plants make use out of sunlight. Amazing.

This video taught me more than my high school teachers did ..It could be explained so simply but still schools dont and just keep us theoritising things

This channel is great. After 30 years, I eventually understood the reason why I had to put my EEPROM with quartz window below UV light to erase it before programming again. Thank you so much!

That was the most wonderfully clean, human, and understandable description of the particle wave duality. And the behavior of electrons, and many other details of particle physics, that I've ever heard. Wow! Wonderfully done sir!

I just turned in a paper on Albert Einstein yesterday!! This effect was one of the sections I included, because of his paper in 1905. How crazy.

I shared this excitingly to my physics teacher... Unfortunately, he read the comments.. I wonder what my grades would be now🤔

Such great teaching videos! Thank you for all the work you put into your presentations. They are the best.

U made it so easy dude , i subscribed to ur channel 2 years ago and i see u r improving day by day with more experiments and their explanation theoretically Great work

I never knew that low frequency radio waves can’t be detected as a particle. That’s really interesting.

I think generally a good goal is to try and not remove or add protons to atoms, that is called nuclear fission or fusion and is generally not a good thing to do near humans

Brilliant demo and explanation. Really loved the explanation of wave particle duality. Thanks for making these films.

Dude, you are amazing. I love your channel! I started watching your channel because of the vacuum chamber thing, but since, I have learnt a lot of other things from you. Thank you!

I literally took up the phone to study photoelectric effect but went to youtube instead and first thing I see is this video . KZfaq can read minds , it's official .

Never knew about this item’s existence!! Thanks for teaching!!!

Probably the best video yet. Great job!

Thank you for this amazing, time-saving demonstration, and for all the time, toil, and treasure you put into making these videos. Can do a lot of good with them, they're great!

I am reading NCERT Book about photo electric effect and you just uploaded a video ,that's awesome

"Because a single photon in the radio frequency... " blew me away

You said something that finally cleared up some confusion for me. All the time when others spoke of light as a particle, as photons, I imagined it as a discrete particle but the way you describe it, as a very short wavelength of electromagnetic energy makes more sense to me, just as a burst of high frequency pulses from a radar transmitter are represented by pulses and not the interwoven cycles of the electromagnetic energy waves that make up the pulse. As an aside, in the "old days" we used to use gas filled tubes such as your neon tube you used as a voltage regulator. Once the discharge potential caused the tube to conduct the voltage drop across the tube would remain the same regardless of the input, within certain parameters.

I learned something and thanks for deepening my understanding of photoelectric effect! Continue to create more contents sir. It really helps to broaden and deepen my knowledge of the lessons. God bless you!

“Mark Twain famously said “I have never let my schooling interfere with my education(now it is KZfaq).” Is it time to reclaim our schools?

The topic is going on in my school thanks for sharing the same

This is absolutely excellent. Especially interesting towards the end when you discuss protocols for calling high energy (high frequency) particulate whilst low energy (low frequency radio waves) we call wavelike. This becomes important in the philosophy of science when we ask what sorts of interpretation should attribute to the background theories. Fantastic stuff. Thank you.

Beautiful 💞 There is so much more to this. More than people might understand.

Literally studied this yesterday and here comes the practical 😀

My school is teaching me about electricity in year 8. However, I completely understand this. Can you be my physics teacher?

8:53 onward was extremely enlightening. the earlier experiment was also very interesting as a practical visual demonstration of how the universe works. I find it totally fascinating that we can actually see the universe's physics like this with such an old-school kind of device.

I’m amazed with your way of explaining. Well taught! I’ll make sure my classmates see this too

I was studying photoelectric effect for my test and suddenly this popped up wow

Dude we just studied this at our school today!!!! Gr8 video btw

This is such a fantastic demonstration, thank you!

I love how smart and wholesome he is. Also he really simplifies it and it help my grandma understand what interests me.

Me starting studying modern physics for my upcoming exam Action Lab : photoelectric effect *Coincidence?. .*

You can make a very simple electroscope with folded in half strip of aluminium foil, if I remember it correctly.

I've heard about the wave/particle aspect of light for 20 years and I've never understood it in the way described here, this was really amazing. A whole new way (to me) of understanding that hard to grasp concept that actually makes some sense.

This is a super, well-informed explaination. Good job :D

I’ve been watching this guy for 5 years and I’d say he’s pretty damn good

Also de broglie gave a nice concept for the wave particle duality

This man have always a whole new idea for his new videos...The explanation is also awesome...Loved it.

I love the way he is so excited about the experiments he does.

This is for me, the best experiment you have done so far. Thank you for sharing, this was very interesting to see. (the mirror room experiment to be fair, was equal to this one. that was cool as hell.)

Yup I totally understood all of that

Thank you for this video. You do an amazing job explaining the concepts.

thank you so much for including the explanation of what we call particles, I wouldn't have thought to look it up by myself and it's very important

I was studying this in my class

When Yt is more valuable than school

Wow, mind blown! Really well explained and visualized.

Congratulations! You're the first person ever to offer a visual demonstration of the reality of electrons. From your hair to the balloon to the plate. I could almost see them getting transferred in their little probabilistic quantum clouds. Awesome 👍😎

So the Sun can discharge things just by looking at it angrily, nice

You have just found a way to not only test the presence of charge! You can now test whether it is positive or negative!

This was simply awesome. I would have loved to have this guy as an instructor in my modern physics & device physics courses. Thank you, sincerely.

How a can person be that much practical !! Love you man 💖

I just studied this in my class 😳

to put it simply, he pushed electrons off a plate using high energy light.

That was your best video yet man, keep doing what your doing.

Such a well demonstration! Amazing! Thanks.

I am studying in 11th and the photoelectric effect is in my syllabus and just this popped up

In my entire life I have never once satisfied with the explanation of static electricity, that is rubbing of things causes exchange of electrons.

I always love your videos sir. Thanks for explaining everything.

I love how you can find endless amounts one content because not only our world is insanely complex but you’re also very creative:)

This remimds me of teslas passive cosmic generator. Only his was copper

When he pulled out short wave UV bulb I literally thought about wearing sunglasses. Yes my brain sometimes evolve backwards for 2 seconds.

Ive heard the wave/particle explanation a million times but the last 30 seconds of the video was extremely facinating because I've never heard it said like that. I kept rewinding it until I could grasp its meaning

Awesome!!! Exactly what I was looking for, thank you so much

Light is composed of waves of oscillating particles.

The "holy cow" never gets old lol

Better every time!!!thanks for wonderful experience

Easily your best video!! Congrats!

Only if this was done when them physicists were arguing if light is a wave or a particle....

Damn I want this guy to be my physics teacher he is too good!!!❤️❤️

It blows my mind how intelligent this man is. Always keeps me coming back to watch move. You’re amazing, keep being you!

Never thought the photoelectric effect could be demonstrated in such a simple method. This guy is genius. 🔥

Loved this channel... From INDIA..🇮🇳

"Hey everyone today I'm going to show you that light is made out of small particles" People who believe light is a wave-"triggered"

Thanks for this incredible class!

Excellent experimental explanation.... God bless you
