Question

explain the term angle of incident and reflection with the help o digram​

Answer 1

Answer

Angle of incidence:-The angle between incident ray and normal.

Angle of reflection:-The angle between reflected ray and normal.

Explanation

When an light ray hits a point in the surface the angle between the light ray and the line perpendicular to that point (normal)

is called Incident Ray.

After hitting the surface this ray get reflected back. The ray which gets reflected back is called Reflected Ray.

The angle between the incident ray and normal is called Angle of incidence.

And the angle between the reflected ray and normal is called Angle of reflection.

Angle of incidence is always equal to angle of reflection
