What is Incident ray, normal and reflective ray ???… …
Answers
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:
What is incident ray:
A ray of light falling on the surface separating two mediums is the incident ray. Refracted ray - A ray of light traveling in another medium, with change in direction is the refracted ray. Angle of incidence - The angle which the incident ray makes with the normal is called angle of incidence.
What is normal ray:
When a line is drawn perpendicular to the reflecting surface at the point of incidence, this line is known as normal. It is the imaginary line which is perpendicular to the reflecting surface. The normal ray is incident at 90 degrees to the reflecting surface.
What is reflective ray:
A ray of light or another form of radiant energy that is thrown back from a nonpermeable or nonabsorbing surface is called reflected ray. The ray of light that bounces back from the surface of reflection is called the reflected ray.
