Light is an electromagnetic wave. Visible light is only a small section of the electromagnetic spectrum. The electromagnetic spectrum stretches from radio.
Reflection and Refraction.  When a wave moves from one medium into another (reaches a boundary) ◦ Speed of the wave changes  More dense  slower  less.
