Definition of the Law of Reflection
The law of reflection states that the angle of incidence is equal to the angle of reflection. When a ray of light strikes a surface, the angle it makes with the normal (a line perpendicular to the surface) is called the angle of incidence. The reflected ray makes an equal angle with the normal, known as the angle of reflection.
