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? 


Let r2 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°

⇒ i2 = 60°

Hence , r2 = 60°

The angle of reflection of incident ray is 60.

  Is there an error in this question or solution?
