Amazing how much I can absorb when the lecture is not boring. Thanks!

Best video on Young's double slit experiment I've seen.

First physics tutorial I have ever witnessed where the narrator isn't talking in endless monotone. For that, you have my unwavering respect, sir.

Never thought optics could be so interesting. Thanks a ton Sir.

I went through 3 physics textbooks and this still didn't make sense! I see your video once and it finally clicks!! Thank you! This helped a lot.

A legendary teacher with such a sweet personality !!

I just love how you explain stuff with a empty paper :). Thank you very much for this contribution to help me study :)

we need more teacher like you!

Haha! Meet infinity - where parallel lines converge. They are certainly parallel and they do keep going, but infinity is a LONG way away. You can get a sense of this by looking at railroad tracks.

You explained this so much better than most other videos I’ve seen, thanks man.

This was an EPIC explanation and I feel like I understand how the entire world works!! Thank you so much for your help!

This was amazing. thank you so much for your time and effort!

You are an amazing teacher :')

thank you for this video. I hate studying for physic test but the way you talk about it is refreshing xD

I AM IN LOVE WITH YOU AFTER BEARING THAT STUPID PHYSICS TEACHER FOR TWO LOOOOONG YEARS AND UNDERSTANDING NOTHING ABOUT WAVE OPTICS! You're a SAVIOUR and I SCREAM that!

oh yes this just saved me over 40 points in my assignment i missed my online class and they offer no video recording just slides and the experiment with no commentary. definitely gonna watch more of his videos very interesting and despite my terrible attention span I was listening intensely which really surprised me :)

So much easier to understand now.. Finally! Thank you.

now that was some great narration!!! Sir you just nailed the YDSE

This is so awesome!! Thanks for breaking it down piece by piece. Physics is fun with your teaching :)

This was awesome! I absorbed the information very well!

dude u made physics way more fun!! I was laughing the whole time lol , and most importantly I understood everything cuz u have a great way of teaching and delivering the information so thanks a lot Doc Schuster !

wow! you make physics so much fun! keep up the good work, thanks!

These are the best physics vids out there!

I'm so glad that I found this channel ....with that laser exp I could understand even more better...we need more physics tr like him :) ^.^

you are the best teacher for college physics courses . You taught physics like a story in jungle book..amazing explanation with such humour.

Holy Holy, mind blowing lesson.

Super helpful!! And fun. Bravo!

Oh my god, you are amazing !!!!! Best teacher ever ! :)

best physics videos on youtube

That's EXACTLY my goal here! Thanks so much for your support.

Am I the only one who thinks he sounds like Barney Stinson from How I Met Your Mother? Thanks for the upload, easy to understand, now I can finish my physics hw.

this may sound totally crazy but i am so touched. i found all this so interesting n i always feel like sleeping in my actual physics class.

Damn! You are great teacher! Loved it!!!

There's a little chromatic separation in person, but it's just a slight hazing of color at the edges. What is really cool is when you put water on the ridged side! I'll make a video of that.

this was a great explanation :) thanks!!

This is lovely!! I have physics exam on this monday and this really helped! actually this is the first time I'm understanding physics instead of learning it algebraic.

Maaan are you amazing!!

yo boss! Great video! Great humour! Keep it up!

thanku so much.....most nyc explaination ever.........

Wow! Physics is beautiful!

Best explanation, thanks!

hey man thank you very much! i've learn so much your teaching style is just awesome! stay cool!

Your videos are so good! I wanna study physics at uni and I find all this stuff so interesting :):)

Thanks!

The Greatest teacher ever 😍

15:54 That's what she said...

I freakin love this doc. Thanks for your wisdom. I have already learned many of the things you teach but you just make it click!

I love this guy. Fun to learn.

You are simply an Awesome teacher, I've tried understanding this on my own from the notes I've wrote in my lecture and i couldn't understand them but then you just saved me, Thank you so much Doc!

Really really really really really really really really really really really really really really really really really really really really really really really really helpful as well as entertaining. Thanks.

Really cool I enjoyed it

you are a very very very good tutor!!!!!

Fun way of teaching man!!I wish all teachers would adopt yours way of teaching then learning could really be fun making.And I wanted to know bright and dark fringes have certain length or they are just points??You havent talked about that!

Awesome!! Thanks to you, I shall pass my physics exams!!

great video thanks

Awesome. I have taken apart another 20 monitors since this video and can confirm that they are prism sheets, and diffusers are behind them. I'll check for diffraction in the spring.

Nice work! Thanks! It's so cool, and I hope every kid and physics teacher takes apart an LCD panel to get one. Careful, though. The thin glass in the screen breaks easily.

Thank you very much sir....

Suddenly a wild marker pen appears at 11:40....

Awesome!!

Are you Neil Patrick Harrison??? Wow, same voice! Thanks for the videos and the enthusiasm, it helps a lot!!

another great vid! super funny

YES! I don't know! It has the most bizarre optical properties, as you can see. I found it in a flat-screen monitor. There's all kinds of cool sheet goods (polarization filter, light diffuser, etc.) in there. I hope someone who knows will be able to answer us, as I am as interested as you are.

Wow! I actually understand things :) Thank you :) :)

thanks alot :) love your teaching

superb very nice

This guy is just too cool to be a Physics teacher😤

honestly this made me laugh and I understood it all- that's a breakthrough

DAMN YOURE SO FUNNYYYYYYY

That was great Doc. Can I please know what that plastic thing is called? Also the second one? Can I get them online? :)

woooaaah! amazing

I love this

What is the explanation for the formation of circular pattern when the incident light is not at right angle to the gratings?

Yay! I'm glad you like physics!

aand ive got unit 2 tomorrow too good!!!

you lowkey sounds like Ryan Reynolds, I love it! Great vid!

I have my Optics exam in 2 days...thanks for making this fun :P!

u r amazing. i love u ♥

Coming from a mathematical background, I loved your set notation. Very useful explanation, thank you. One question, if both rays have an angle theta, how come they will converge as they are parallel?

Wonderfully explained doctor... but i am confused with the formula of destructive interference , you have written it something like this (m-1/2)lambda ,but as i have studied it seems like this (m-1/2)lambda. please sir make me correct..

what material was the sheet at last? it looked so cool

I think you can get to my google plus account from youtube. I don't have another page per se.

Better than my physics teacher , much obliged =V=

When you clean you're shower with baking soda and vinegar when it goes down you're pipes will it break you're pipes or when you wash it off with water does that neutralize it

Man. This is awesome. I'm subscribing. Question:I'm trying make a video, an Elegant way to describe gravity, dark energy, black holes and quantum fluctuations all in one: Take a rubber membrane and suck on it using a vacuum cleaner. It creates balloon. From the outside, the membrane mimics gravity sucking space time to form a black hole. From the surface inside the balloon, the membrane mimics the expansion of universe due to a mysterious dark energy. Obviously both gravity and dark energy are the same thing looked from different angle. They are both caused by the energy differential on each side of the membrane. The energy differential is, at small scale, called quantum fluctuations. At large-scale it is called a black hole or a white hole/big bang Then i go in quantum gravity. When energy of quantum fluctuations are locally not equal and thus generates a flow. Same principle as Hawking radiation. It separates virtual particles like the waves separates the sand in the beach according to size and weight. Is that a good illustration of all of the topics in one? Thank you for your time. And have a great day.

lol you still can see a smiley on the left hand :D

...and thanks to YOU! I'm not the guy who's going to pass his physics exam - you are! Go get 'em.

Sure. There are a lot of variables here, and it's too easy to become confused. Delta l is path-length difference from the two sources. d is separation of the slits. Neither of these is the separation between the fringes, which depends on how far the screen is. You are most interested in theta, which is how I am measuring [angular] fringe separation. To increase theta, either decrease d or increase lambda. I hope this is also conceptually consistent.

Can someone help me please. In some notebooks for destructive interference it says that delta l=(2m-1)*lambda/2 and in other there is plus sign after m. Help!

Hi, thanks for the video. You are a great educator. Around 6:58 you mention that the angle between the normal to the first slit and the diffracted ray from the first slit is equal to the angle between the normal to the first diffracted ray and the line containing the slits. We can see this intuitively, but is there a specific name or term for the argument which proves this equality?

Hey Doc, amazing video. I definitely learned a lot in these 17 minutes. I just have this one doubt. See,you said that the light waves(let's call them waves) coming out of the slits were spherical. But shouldn't they be forming a cylindrical wavefront according to Huygen's Principle? Please just explain this. Loved the video. Instant subscribe!

It is insane to think about how early Young came up with this experiment.

amazing explanation. I just want to ask why did he not pass the filtered light from the double slits from the beginning?why did he pass it from a single slit first?

Where have you got that plastic sheet (as slit (s))? And laser light too.......

Awesome tutorial sir!!!One Question During laser tricks session if we use white light what do we expect rainbow fringes or no interference?

this is a right angle my hommies LOL nice video

God.. I finally got it after 2 years

Equation for destructive wave is it [(m-1/2)*wavelength] or is it [(m+1/2)*wavelength]?

Wow!!! thos hands!!

I think that those green circles are the wavefronts and the dots in the circle is the point source of secondary wavelets...
