Question

Two plane mirrors are placed perpendicular to each other.

An incident ray strikes the first mirror at an angle of 43˚. Explain
the path of the reflected ray from the second mirror with the help

of a diagram​

Answer 1

Explanation:

Let ray strikes the vertical mirror by angle of incidence θ. Then by joining the perpendiculars of two mirrors it is clear from the diagram that angle of incidence at horizontal mirror is (90−θ).

∴ reflected ray from horizontal mirror makes angle θ with the horizontal mirror also incident ray at vertical mirror makes angle θ with horizontal axis.

∴ reflected ray is parallel to the original ray.

This is true for two perpendicular mirrors fixed at any positions.
