Question

Draw a figure describing the following. The reflecting surface of two mirrors make an angle of 90∘ with each other. If a ray incident of one mirror has an angle of incidents of 30∘, draw the ray reflected from the second mirror. What will be its angle of reflection?​

Answer 1

Answer:

Let r2 be the angle of reflection from the second mirror.

From laws of reflection :

∠i1=∠r1=30∘ 

Now in Δ ABC 

θ=180∘−90∘−60∘=30∘ 

⇒i2=60∘

Here , r2=60∘

The angle of reflection of incident ray at second mirror is 60∘ .

this is ur ans...

Answer 2

60 degree angle
