Question

the angle between the incident ray and reflected ray is 100° what is the value of angle of incident
​

Answer 1

Answer:

So the angle between both the angle of incidence and angle ofreflection is 50 + 50 = 100 degrees.

Answer 2

Answer:

∠i + ∠r = 100°

Since, ∠i = ∠r

∴ ∠i + ∠i = 100°

⇒ 2 ∠i = 100°

⇒ ∠i = 100∘/2 = 50

∴ Angle of incidence = 50°.
