Question

what is the the difference between reflected and incident rays

Answer 1

The incident ray is the ray that strikes the given surface at the point of incidence.

Whereas

The reflected ray the ray reflected from the point of incidence.

Remember : the normal is the perpendicular drawn at the point of incidence.

Also,
Angle of incidence = angle of reflection
angle of incidence is the angle formed by incident ray and normal whereas angle of reflection is the angle formed by the reflected ray and normal.
