Laws of Reflection
In the Figure Illustrates the terms that we use in the study of reflected
light.
Represents the surface of a plane. AO, called the incident ray, is the
direction in which light falls onto the reflecting surface. O is the point
of incidence and OR the, reflected ray. The angles, which the incident
and reflected rays make with ON, the normal or perpendicular to the
reflected surface at the point of incidence, are, called the angles of
incidence and reflection respectively. Laws of reflection are -
♦ The incidence ray, the reflected ray and the normal at the point of
incidence all lie in the same plane.
♦ The angle of incidence is equal to the angle of reflection.
