Question

Q Define:
Reflection​

Answer 1

when a ray of light coming from an object falls on a polished/ shining surface, this ray of light is known as INCIDENT RAY. when the light falls on the particular point of the shining surface that point is denoted as point of incidence. this ray of light then gets reflected, this ray of light which gets reflected from point of incidence is known as reflected ray. This phenomenon is known as reflection of light..

An imaginary line is drawn by scientists to understand about reflection of light. this line is known as normal.At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. This line is known as a normal.

Angle between incident ray and normal at the point of incidence is known as ANGLE OF INCIDENCE.

Angle between the normal and the reflected ray at the point of incidence are known as ANGLE OF REFLECTION.

LAWS OF REFLECTION

there are 2 laws of reflection. these are as follows:-

1. angle of incidence= angle of reflection.
2. Incident ray, normal and reflected ray all lies in same plane.
