Question

A ray of light strikes a plane mirror XY at an angle of incidence of 65 degree is reflected from this plain mirror and then strikes a second plane mirror YZ placed at right angle to the first mirror. What is the angle of reflection for the mirror ZY? EXPLAIN WITH THE HELP OF A DIAGRAM

Answer 1

A ray of light strikes a plane mirror XY at an angle of incidence of 65 degree is reflected from this plain mirror and then strikes a second plane mirror YZ placed at right angle to the first mirror.

Incident and reflected angle for mirror XY is 65°

From ∆MYN, angle MNY = 65°.

So incident angle for YZ is 25°

So reflected angle = 25° for mirror YZ.
