Front

What is the definition of a wave?

Back

A wave is a disturbance that transfers energy from one place to another.

Front

What happens to light when it hits a reflective surface?

Back

It bounces off the surface at the same angle as it hit it (angle of incidence = angle of reflection).

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another.
