Question

if a Ray of light is incident perpendicularly on a plane mirror the angle of incidence will be and how​

Answer 1

Answer:

For a plane mirror: If the incident rayfalls along the normal, the angle of incidence is 0 degrees, NOT 90 degrees. The angle is measured with the normal to the mirror and not with the plane of the mirror. Hence theangle of reflection is equal to 0 degrees.
