Question

write a note on normal incidence for reflection of light​

Answer 1

hey

The law of reflection states that theincident ray, the reflected ray, and thenormal to the surface of the mirror all lie in the same plane. Furthermore, the angle of reflection is equal to the angle ofincidence . Both angles are measured with respect to the normal to the mirror.

Answer 2

The condition in which a wave-front is parallel to an interface, such that the ray path is perpendicular (normal) to the surface. The angle of incidence is zero.

The normal line divides the angle between the incident ray and the reflected ray into two equal angles. ... The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
