What is Incident ray, normal and reflective ray ???…
Answers
Answer:
Incident ray :
The ray of light falling on the surface AB is called the incident ray.
Reflected ray :
The incident ray bouncing back in the same medium after striking the reflecting surface is called reflected ray.
Normal :
It is the line drawn perpendicular to the reflecting surface at the point of incidence.
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.
