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.

This is still helpful 6 years later. Thanks!

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!

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

[mmehana]

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

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

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?

[sasidharreddy]

you solved one of my biggest question that i have from past one weak.
thank you so much sir

[honey]

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

[kamalasangiri]

1:58 what you seem to be saying is that with a tiny enough slit in the wall, you will be able to see the light coming through it even when standing completely off to the side, adjacent to the wall.

How on earth!!! My teachers used up all my pages to draw god knows what! N u just write down 4 words! N I understand EVERYTHING! THIS IS VERY VERY VERY HELPFUL!!!!

[linaandersson]

THANK YOU for saving me throughout my university degree, and explaining things in a very EASY to understand-way, unlike my actual teachers😂

[ShaggytheRodgers]

Very, very helpful man. Wikipedia has got nothing on you.

Great video i really hated diffraction when i was at school thanks for the explanation
