Refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed.

Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated.

A substance that makes possible the transfer of energy from one location to another, especially through waves.
