I Have This Physics Question- Two plane mirrors are kept at right angles and a beam of light is made incident on mirror '1'. If a third mirror is now place at an angle 90 degrees to the second mirror (mirror '2') what will be the angle of reflection of the reflected ray from mirror 3. How?

apply simple laws of reflection....i=r  and a bit of geometry

u will end up with this.....if the initial angle of incidence was 'i' ,,then the final angle of refraction would be 'i' itself........(just apply angle sum property and complementary angles property)
