Question

10. What are the values of the angle of incidence and the
angle of reflection for normal incidence on a plane mirror ?
​

Answer 1

Answer:

It is 0 degree

Explanation:

For a plane mirror the angle of incidence and angle of reflection is same. So for normal incidence the angle of incidence with the normal is 0 degree and therefore the angle of reflection also.

Answer 2

For a plane mirror the angle of incidence and angle of reflection is same. So for normal incidence the angle of incidence with the normal is 0 degree and therefore the angle of reflection also.
