Question

What is the angle of incidence and reflection when a ray falls normal?

Answer 1

Answer: 0 degree

Explanation: because when a ray goes a long normal it reflects back though same normal so both angles are zero

Answer 2

✔Normal is the line making 90° angle with a particular point on mirror and angle of incidence and reflection are the angle made ny of light with normal. Here the light ray falls normally, therefore theangle of incidence is following the same path of normal and hence the angle is zero.
