Question

incident angle of a ray of light is 30.The angle between the incident ray and the reflected ray is​

Answer 1

Answer:

Explanation: Ray is making 30° with the mirror. Hence angle of incidence = 90 – 30 = 60° angle of incidence = angle of reflection = 60°.

Answer 2

Answer: 60°

Explanation:

Given that:

Angle of incidence = ∠$i$= 30°

Angle of incidence = Angle between the incident ray and the normal.

According to the laws of reflection,

Angle of incidence = ∠$i$ = Angle of reflection = ∠$r$

⇒ ∠$i$ = ∠$r$

⇒ ∠$r = 30$°

Angle of reflection = Ange between the reflected ray and the normal.

∴ Angle between the incident ray and the reflected ray

= ∠$i +$ ∠$r$

= 30° + 30°

= 60°

Hope you got that.

Thank You.
