Question

A light ray incident on a plane mirror. If the angular deviation is equal to the angle of incidence,what is the angle of glancing

Answer 1

$\large\blue{heya mate!!}$

The total angle between the straight-line path and the reflected ray is twice the angle of incidence. This is called the. The angle of deviation in plane mirror is equal to the twice of glancing angle .

Answer 2

the total angle between the straight line path and the reflected ray is twice the angle of incidence.this is called the angle of deviation in plane mirror.it is equal to the twice of the glancing angle.
