Question

The angle between the incident ray and the reflected ray is 60°. What is the value of angle of incidence?

Answer 1

Answer:

30 degree

Explanation:

angle between incident and reflected ray =2×angle of incidence or angle of reflection.

Answer 2

Answer:

The Angle of incidence will be 30°

Explanation:

The Angle of Incidence = Angle of reflection

According to the question we can make a diagram which will look like as above

so we can write

angle i + angle r = 60°

angle i + angle r = 60°angle i +angle i = 60° (angle i = angle r)

angle i + angle r = 60°angle i +angle i = 60° (angle i = angle r) 2(angle i) = 60°

angle i + angle r = 60°angle i +angle i = 60° (angle i = angle r) 2(angle i) = 60°angle i = 30°
