The law of reflection states that: angle of incidence i = angle of reflection r. For example, if a light ray hits a surface with an angle of incidence of 45°, it will be reflected with an angle ...

Refraction is the bending of light rays. Normally, light travels in a straight line, and changes direction and speed when it passes from one transparent medium to another, such as from air into glass.

Reflection and refraction occur whenever light encounters a material at an angle, because one side of the beam is able to race ahead of the other. As a result, the wavefront changes direction.
