Question

what is angle of incidence and angle of reflection​

Answer 1

Answer:

When light is reflected from a surface, the angle of incidence is always equal to the angle of reflection, where both angles are measured from the path of the light to the normal to the surface at the point at which light strikes the surface. This equality is known as the law of reflection.

Answer 2

Hey there!!

the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal

the angle of reflection is the angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface
