3.14 Light waves

Lightwaves are transverse and they can be reflected, refracted and diffracted


Definition:
Refraction: The bending of light when it passes between materials of different density.
Reflection: The change in direction of a light wave so that it returns into medium from which it originated.
Diffraction: Waves spreading into the shadow when they pass an edge.
