Refraction changes light's direction when it moves between mediums. Reflection occurs when light bounces off a surface, like a lake reflecting mountains. Absorption happens when a material, such as trees or rocks, soaks up light and doesn't reflect or transmit it.

Diffuse reflection, which occurs with rougher surfaces, scatters light rays in different directions. The video also introduces double reflection, which occurs when light reflects off of one surface and then reflects off of another surface before reaching your eye.
