Answer 2

Answer :-

• Incident ray :- The ray of light which strikes the mirror.
• Normal :- Imaginary line which is perpendicular to the point at which the incident ray strikes.
• Reflective ray :- The ray of light which reflects back after the incident ray strikes the mirror.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

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.
