Question

If the angle of incidence of a ray of light is 42°, what is each of the following? a) the angle of
reflection b) the angle the incident ray makes with the mirror. c) the angle between the incident
ray and the reflected ray.​

Answer 1

Answer:

a) 42° b)48°c)84°

Explanation:

a) according to laws of reflection

angle of incidence= angle of reflection

angle of reflection=42°

b) angle of normal ray with mirror is 90°

angle made by incident ray to the mirror= angle with normal - angle of incidence

= 90-42°

= 48°

c) angle between incident ray and reflected ray = sum of angle of incidence and angle of reflection

= 42° + 42°

= 84°
