Question

explain briefly about incident ray, reflected ray, point of incidence, normal, angle of incidence, and angle of reflection.

Answer 1

angle made by a reflected ray with a perpendicular to the reflecting surface.

Answer 2

INCIDENT RAY :

A ray of light falling on a reflecting surface such as mirror is called the incident ray .

POINT OF INCIDENCE :

The point at which the incident ray strikes the reflecting surface is called the point of incidence.

NORMAL :

The line drawn perpendicular to the surface at the point of incidence is called normal

ANGLE OF INCIDENCE :

The angl between the incident ray and normal is called the angle of incidence.

ANGLE OF REFLECTION :

The angle between the reflected ray and normal is the angle of reflection.

hope that helps !!!
