Wave Diffraction

110 - Wave Diffraction
In this video Paul Andersen explains how waves will diffract (or bend) around an obstacle or while traveling through and opening. Diffraction will be maximized when the size of the opening or obstacle matches the wavelength.

You're telling me he teaches this good without us paying him anything and then there's our teachers...

[@lwinklly]

whos else watching in physics class!"!!!"!!?!?!?

[@KMirmil]

Why does the wave diffract so big when the gap is smaller than wavelenght? What is the connection between gap and wavelength? Why it is like that?

[@supersonic174]

doesn't actually explain why the waves diffract.

[@abcdefg-ub5qm]

im watching 9 years later

[@naosheyrvaannasir5047]

what an effective video! its at a steady pace which makes it easy to learn and the explanation is crystal

[@Isaac.Garcia]

Thank you, Mr. Bozeman

[@tjtalksrandom5789]

Thanks a lot

[@IshaqKhan-ev8gq]

Thank you Sir

[@sairafarooq6027]

Hello sir I have a question how would we know the wavelength? That the size of obstacle is of same as the wavelength I mean how would we know but visual representation?

[@-MikaelaWuisan]

Best video ever!!! Thank you so much for helping me clear up my doubts! Initially, I was confused whether my understanding about the gap being the same size as the wavelength, but the video cleared everything up! So it literally meant that if the gap was = to lambda then true diffraction (like the ones with a lot of bends) can be seen!

[@anythingunderthesun9930]

Now this channel really explains DIFFRACTION that is easy to understand. Thanks and KUDOS!

[@Abdullah-fc4tm]

This is still helpful 6 years later. Thanks!

[@prabhnoor_]

Great video.... really clear and thorough...thank you for clearing up a great and interesting concept

[@sasidharreddy2846]

you solved one of my biggest question that i have from past one weak.

[@doseoffaiyaz]

Excellent! I was confused and was sitting idle for half an hour trying to figure it out and my search results weren't helping.

[@onlyanjan99]

Too good an explanation Sir. Very helpful. Thank you!

[@mmehana]

I could not thank you enough! Thanks so much :)

[@litasmith2472]

Thank you for making it simple to understand.

[@marcioadames9956]

Amazing video. Very objective and clear. Thanks Bozeman.
