Everyone's talking about their finals or whatever but I'm here because of my online classes while quarantine

pov: you have a frequency test tomorrow and you've just been playing video games during physics class

I'm in a grad program for speech pathology and this video helped me understand concepts that my professor couldn't communicate thoroughly in two hours. Thank you so much!

Nobody can explain things better then this guy

Haven't been able to understand this for a full semester. A minute and 56 seconds into this video and now I have these concepts crystal clear. Idk who you are but ily.

What you did in 4.89 minutes (approx.) is what takes a period of 4 days. Awesome explanation sir👍👍👍👍👍👍👍👍👍👍

you have literally saved my life. I have an exam tomorrow and I dint understand the relation between period and frequency.thank you for helping me understand this concept.

The final is tomorrow, so thank you. my teacher just sort of stopped teaching

Hi, just wanted to say thanks for this very clear explanation, it has really helped me to grasp the basics of the relationship between wave period and freq, I hadn't seen your previous videos but will deffo be checking them out to see if there's any other topics I need to understand better for my coursework. Especially if you have any Algebra vids. I was doing fine with Mathematics until the alphabet got involved... I am studying towards a degree in Computing and IT with Open University (studying from home with lectures online). I have no school qualifications, but I'm doing OK so far. One of the compulsory modules of the degree is to choose between 'Discovering Mathematics' and 'Essential Mathematics', essential mathematics is a follow up to A-level students here in UK and was way too advanced for me so I started Discovering Mathematics - I wasn't prepared for mathematics to be such an important part of the computing course before hand so have been thrown in at the deep end before I can swim in regards to the mathematics side of things. Anyway I have been doing alright, but one of my assignment questions has asked something like: to calculate the period of a Sine wave when given the frequency, and to then half the result (period) and explain/calculate what then happens to the frequency. Your video gave me a clear insight and cool visual explanation of it all with the light bulbs and really helped so want to say a big Thank You!

Thank you!! I have midterms in a week and now I feel prepared because of your video

Thank you so much for explaining these relationships so clearly! I understand them now :)

couldn't be easier than this video to learn about frequencies. Thank you

You are a very good teacher,simple explanation that captures everything

My final exam is in 1 day. This man just saved my life.

Have a Physics Exam Tomorrow and this helped a lot, Tysm

You explained this perfectly, thank you!

Thank you so much! I just could not grasp this the way my teacher was teaching us. The flashing light bulb really helped.

Thank you so much for explaining this with videos of waves to see what it physically is, it makes much more sense!

Amazing i am studying in STD 8 and was just here to study a bit during quarantine from india

Wow... thank you so much. I just learnt the most challenging topic on tomorrow's test in 5 minutes

i wish this guy was my physics teacher , in fact for all my subjects lol. you make it so easy. thanks

*mindblown* Did anyone else's head explode at the end?

DAMN, MY FINAL IS TOMORROW THANKS TO THIS DUDE WHO SAVED MY LIFE

I love this man and how well he explained this

thank you for making me understand this in 5 minutes while my teacher couldn't even teach me this in 3 days.

great video you just helped a student in switzerland

thankyou so much this helped me a lot, especially now there is a pandemic and we are doing modular instead of online class. We are studying by ourselves.

You just made my physics exams easier. Thanks :)

Thank you I had hard time getting my mind around this topic until now.

Thankyou so much this was extremely helpful :)

Thanks man ur a life saver I have a test u saved me

Perfectly explained! Thank you!

Thank u sir 🥺I really needed this

very helpful. thanks dude

This was very helpful. Thank you.

Great explanation for the RSGB Intermediate exam.

exam in an hour you saved me, and i am not a crammer i just didnt clearly understand this part of my notes

Excellent stuff. Cleared up any confusion. 👍👏👏👏

Your awesome! Great teaching Skills

Thank you so much, sir. It means a lot fr such expressions. Keep teaching us.

Excellent explanation, very helpful

Nice and simple, thanks! Reviewing for Fourier analysis course. Sometimes you forget the little things :-D

Thanks ,Another important part that I wanted to know is which is more powerful,a short wave or a long wave,and does length affect the speed? Are there any good applications for the slower, weaker wavelength,whichever that one might be?

super cool and helpful so wait is this for all waves? does it apply to sound as well as light? or are there other rules for sound waves ?

thx for this vid it was explained in a simple way but i got so much

Thanks for making this so easy to understand!!

man you helped me a lot with my physics homeowkrd

i was googling feminist frequency and i ended up in this video! Now i understand things better thank you!

I’m lucky i have a test next hour and i just have to know this really thank you EDIT: got an 7,4 soo thanks bud

Omg u are a life saver i love u

Will you explain Fourier transform or any simillar subject from "difficult physics"?

this is extremely helpful and thank you

Shouldn’t your graph be starting at the origin if the period is 20 sec? Graph goes through (20,0), so should go through (0,0) too.

You really help me thanks

Tensor variations in the confines of one photon in time based on medium optical density, for those who know that light is energy with no mass.

Thankyou

Thank you.

so a period is the time in between waves right? Or is it the time taken for a full oscillation?

Omg this guy is amazing, I wish my professor were like him u.u

THANKS for the information I Got from this Video

just what i needed thank you great video

يا لبى قلبك . thank you very very very much

Wow man, tanks a lot, i like this channel.Have a nice day

You just helped my kid! Thank you! 😁

What exactly is period of a sine wave? When we describe it on an axsis, will the period be 2pi Second or 2pi Radian?

if the period of a tone is in milliseconds, is it still 1 divided by that number? In other words, is it always 1 divided by the period or is T in seconds?

How do I find the period of the waves? pls help me I͜͡ n͜͡e͜͡e͜͡d͜͡ i͜͡t͜͡

very helpful and easy to understand

Question, with your first lightbulb example you say the period is one second long however you did not include the time when the lightbulb is off as part of the cycle. Shouldn't the cycle include the time it is on plus the time it is off before it is turned on again?

This lesson hit me emotionally 😭

thanks for the video it was really helpful

This was so helpful! Thank you.

This video was awesome. Thanks alot

Thank you for the examples, this was a welcome and helpful refresher!

Can I use your idea in this video for our short presentation in our school? It's like I'm going to recreate some parts of your animation in the video to be included in mine?

Very good explanation

So on successive waves i can use the trough on one wave and the trough on the next wave to calculate the period ?

very very helpful thanks

Amazing video man!

Yes, It was helpful, Thank you.

Great explanation thanks

That was very helpful

Thanks, man I understand clearly

helpful!

You have almost 1Million subscriber!

Thank you so much this video helped

Very good video.

I know am radio means amplitude modulation and FM radio means frequency modulation and the music we hear is vibrations I'm trying to figure out the difference between radio music vibrations and wifi using the same system or close to the same system I know one difference between music and wifi is wifi signals reach the speed of light and radio signals to not there are several factors in the electromagnetic spectrum being factored in wavelength frequency hertz vibration energy and speed I wasn't sure if there were any other factors than those because a detailed picture is a lot more complicated than detailed sound especially when you can trade information back and forth thank you if you can explain it

thank buddy ......this vid is really helpful

Love this man

THIS SAVED ME

Thank you, helped alot !!!

Thank you sir!

Good teaching

Can you explain the weak nuclear force...?

why am I learning this is 6th i’m crying rn I don’t get ittt how can I find period based on a given frequency?

that was helpful

veery helpful! thank you!

ty for the carry I need this for crave the wave the scioly event

My teacher literally quit, so I have to come here to pass bc we haven’t learned the new assignments
