Light Is Waves: Crash Course Physics
The way light behaves can seem very counter intuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make more sense! In this episode of Crash Course Physics, Shini shows us how we know...

Diffraction Effects
In this video Paul Andersen explains how diffraction can be affected by the size of the wavelength. When waves pass through an opening or move around an obstacle a shadow region is created. The size of the shadow zone will decrease as...

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.

Interference Patterns
In this video Paul Andersen explains how constructive and destructive interference can create interference patterns. Interference patterns can be created by all types of waves, including water, sound, and light. A classic experiment that...
