Question

if a incident ray is making an angel of 90° with the surface of a medium UI angel of incidence​

Answer 1

Explanation:

The angle of incidence is measured with respect to the normal drawn at the point of incidence.

The angle of incidence is measured with respect to the normal drawn at the point of incidence.The incident ray makes an angle of 900 with the mirror surface.

The angle of incidence is measured with respect to the normal drawn at the point of incidence.The incident ray makes an angle of 900 with the mirror surface.So, angle of incidence =(900−900)=00

The angle of incidence is measured with respect to the normal drawn at the point of incidence.The incident ray makes an angle of 900 with the mirror surface.So, angle of incidence =(900−900)=00According to the laws of reflection, the angle of incidence is equal to the angle of reflection.
