Question

b) The angle between the incident ray and reflected ray is 100% What is the value of angle of incidence
​

Answer 1

Answer:

angle of incidence=angle of reflected ray

angle of incidence is 50%

Angle of reflection is 50%

Answer 2

Explanation:

∠i + ∠r = 100°

Since, ∠i = ∠r

∴ ∠i + ∠i = 100°

⇒ 2 ∠i = 100°

⇒ ∠i = 100∘/2 = 50

∴ Angle of incidence = 50°.
