It is also known as the law of refraction. Snell's law is a formula used to describe the relationship between the angles of incidence and refraction; when referring to light or other waves passing through a boundary between two different isotropic media such as water, glass and air.

Answer:
The normal line divides the angle between the incident ray and the reflected ray into two equal angles. ... The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
