Question

(b) Light is incident on a flat surface, making an angle of 30° with that surface, as shown in the
figure. (1) What is the angle of incidence? (ii) What is the angle of reflection?
30°​

Answer 1

Answer:

Angle of incidence=30°

angle of reflection=30°

because angle of incidence= angle of reflection

Answer 2

Answer:

Angle of Incidence = 70o

Angle of Reflection = 70o

Explanation:

Angle of Incidence is the same as Angle of Reflection

Or Angle of Incidence = Angle of Reflection as a reflection is always same
