Point of incidence :- The point at which the incident ray strikes the mirror is known as the point of incidence.
Angle of incidence :- The angle which the incident ray makes with the normal is known as the angle of incidence. It is generally denoted by i.
Angle of reflection :- The angle which the reflected ray makes with the normal is known as the angle of reflection. It is generally denoted by r.
________________________________
⛳ The incident ray, the normal at the point of incidence and the reflected ray – all lie in the same plane.
⛳ The angle of incidence is always equal to the angle of reflection i.e, <i = <r.
