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» 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...
