Laws Of Reflection

Reflection takes place according to certain definite laws known as the laws of reflection. The laws of reflection hold good for all types of surfaces—plane or spherical.

First Law of Reflection
During reflection, the incident ray, the reflected ray and the normal at the point of incidence all lie in the same plane. In Figure 9.3 incident ray PO, reflected ray OQ and the normal ON, all lie in the same plane.

Second Law of Reflection
When a ray of light falls on the reflecting surface, the angle of incidence is equal to the angle of reflection, i.e., i = r.
