Question

in a plane mirror which is the measure of the angle of incidence the angle between the mirror and incident ray on 90 degree minus the angle between the mirror and the incident ray​

Answer 1

Answer:

The angle between the mirror and the incident ray is 30 degrees. The sum of the angle of incidence and this angle (30) makes a right angle. So, the angle of incidence is 90 - 30 = 60 degrees. As the angle of incidence and the angle of reflection are equal, both angles equal 60 degrees.
