#### 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?

#### Solution

Let r_{2} be the angle of reflection from the second mirror.

From laws of reflection,

`angle i _1 = angle r_1 = 30° `

Now in `triangle` ABC

θ = 180° - 90° - 60° = 30°

⇒ i_{2} = 60°

Hence , r_{2} = 60°

The angle of reflection of incident ray is 60^{∘}.
