Question

what are the values of (i) angle of incidence and (r) angle of reflection for a normal incidence​

Answer 1

Answer:

When a ray of light is incident normallyon a plane mirror it means that theangle of incidence is 0ₒ. From the law of reflection, we find that angle of reflection is also 0ₒ.Thus, for normal incidence on a plane mirror, angle of incidence and angle of reflection are 0ₒ
