3.14 Light waves

Light waves are transverse waves which can be reflected, refracted and diffracted

Reflection of light: The change in direction of a light wave so that it returns into medium from which it originated

Refraction of light: The bending of light,when it passes between materials of different density e.g from air to perspex:

 

Diffraction of light: Light Waves spreading into the shadow when they pass the edge or through a slit.
