Question

The angle of incidence is 42 ⁰. Then the angle between incident ray and mirror is​

Answer 1

Angle between incident ray and mirror is 132 degrees

Answer 2

Answer:

angle of normal is 90°

then

angle of incident ray and mirror = 90° - angle of incidence

angle of incident ray and mirror = 90° - 42°

angle of incident ray and mirror = 48°
