Question

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

Answer 1

Answer:

Explanation:

For normal incidence, the incident ray is along the normal itself. So the angle of incidence is 0. From the laws of reflection, the angle of incidence is equal to the angle of reflection. So, the angle of reflection is also 0.
