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.

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

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!

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.

What if due to multiple points in the slit region, the waves interfere with each other destructively and only a small number of them are constructively interfered?

I think these curves in waves appear because the ends of each wave lose kinetic energy, therefore moving each part of the wave moves at different speeds. Now, in the case of light, this still happens, but light doesn't bend. So what causes this. Correct me please.
