8.02x - Lect 26 Traveling Waves, Standing Waves, Musical Instruments

his lectures always recover my passion for physics again after weeks of unintuitive lessons from my physics class

amazing! 👏👏👏

Exactly how physics should be presented

i did not understand how the wave was created by a rotating wheel. Won't the string just twine to the wheel?

Sir, you are more than amazing.your presentation made me love physics.❤️❤️❤️❤️❤️❤️❤️

Had to tune the violin everyday in wisconsin!

what a guy!

What is 803

So far I was wondering how the standing wave phenomenon possible. My mind was a mess. Now it's cristal clear how this bizarre thing happens. Thank you so much professor. I love you so much ♥️♥️♥️

Thank you sir

Wow! With this teacher everyone would want to be a physicist!

I will never forget you Professor Walter Lewin. You are the only physicist that taught Physics with great care and thoroughness in terms concept. Your demonstration proves extremely valuable that registers in my mind. I thank God for your life, and contribution to teaching physics in a way that makes me appreciate and love Physics. You enlightened me of all the topics that I didn’t really understand the concept well, or sometimes not at all because of lack of faculty by others. You are such a gift in the world of Physics. Thank you Professor 🙏.

Sir here why you take moving graph firstly and how you thought that for positive x direction we should take minus t and vice-versa?....

Thank you for these amazing classes ❣️😊❣️

perfect lecture

Love you sir .... ☺️

Watch this Lecture and listen to Kind of Blue. Preferably at the same time.

Thank you, professor!

This teacher can inspire anyone to learn physics. I myself am inspired by him. This is my channel about Science.

This was actually a decent Ysaye

Now bring on some Heavy MeTaL Musicians 😁🤟

Enjoyed a lot this lecture while learning!❤️

hello Mr Lewin ,
I'm a french cityzen and i'd like to know what means 8.02 and 8.03 ? of cours I understand that's a matter of level ,could you telle me more ? for instance in france we'v got Math sup and Math spe (1st year and 2nd year of math physisc and chemistry high level) and also in university 3 years licnse 4 /years master,5y+ doctorat (Phd in US)
thanks and i'm fan of your lessons ,you suceded in melting pragmatical experiences linked cleverly with théory !

by the way I have another question about electromagnetism and elctrom. waves : how is it possible that E and Bto be immediatly linked in space propagation , why is there no" delay" between variation of one regarding the other ,why is it "instantly" ?
thanks again

Amazing lecture

Many Thank You for the Great job you have done! Probably the only clear explanation (at least for me) of the standing waves that I have come across. Bless you!

Blessed to witness these lectures, sir! It gives me eternal happiness

I don't know if my comment has posted or not I've tried so many times

In reed based woodwinds instruments, e.g. clarinet or saxophone, if one blowconstantly on a note, theb open the register hole which eliminate the fubdamental freq so you get a note in hugher octave but then you close the hole and magically you do not get the low fundamental as long as you continue blowing air in. Only when one stops and dtart again the low fundamental freq appears again. I wonder why?

Can any one tell me why is this so easy with this guy 😀

Watching the legend in 2023. ❤

Beautiful!

I like this. this is cool

Not string theory it's a wave like the ocean 🌊 that would be a better example

You are an incredible teacher and a wonderful human being. You involved your students in the lecture and gave them a chance to demonstrate their talents to everyone. Very rarely is this the case - most teachers are content showing off their own talents (if even that). I will remember this lesson - to give others the chance to impress me - because you never know what amazing talents people have hidden.

I like the way you tie the mathematics to physical demonstrations. It is all to easy to to get lost in mathematics and lose sight of the physics.

Best presentation professor

which song did he play on saxophone ?1
if anyone knows please comment

THE ORIGIN IS EQUI POTENTIAL WITH DIFFERENT NECESSARY ATTRIBUTE !

Why is the period 2 pi / ω ?

What does he mean with N stands for Nancy?

Respect for Sir Walter Lewin from Pakistan 🎉

🎉❤🎉❤🎉❤🎉❤🎉❤🎉❤

A lecture AND a concert? Now that's some real value for your money! 😂

Sir, great fan 🫡. I would like to know about the rope you've used and what kind is ideal for this demo. e.g., Plastic/Nylon ones are too rigid to show the reflection and standing waves.

Any suggestion will be highly appreciated

Love from Pakistan🇵🇰❤

How does the mass or density of the bow fibers affect the frequency vibration of the violin string?

What aree the string in the larynx that vibrate analogously?

Sir can you please tell me
Doubt --> if the intensity of light changes when we put it in different medium "this doubt is from wave optics"
My teacher is saying no it will not change
But we have relation I=2π²n²ρvA²

So can you clear my doubt

if I am assuming young double slit experiment and I change the medium of one and the other one is air will ithe intensity of light still be affected?

Damn sir.. i really aspire to be a teacher like you some day.. only if I could become half as cool a you… .. just completed shm and waves from my batch.. but the way you presented them is just on a whole other level.. thankyou for existing…🫶🏼
