Question

What is Incident ray, normal and reflective ray ???

…

Answer 1

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.

Answer 2

Answer:

Incident ray - the ray of light falling on the surface AB is called the incident ray. ... Angle of reflection - the angle formed between the normal and the reflected ray is called angle of reflection. Normal - it is the line drawn perpendicular to the reflecting surface at the point of incidence.
