Question

Table 16.1 : Angles of Incidence
and Reflection
Angle of
Incidence (Zi) Reflection (Zr)
Angle of
O.​

Answer 1

Answer:

When the light ray is incident normally on plane mirror surface it means the angle between mirror surface and light ray is 90°.

This means the angle between incident light ray and normal is 0º which is called angle of incidence.

As angle of incidence is 0° angle of refelection is also 0°. ( By law of reflection of light)
