Question

A Ray of light is incident on a plane mirror at an angle of 50 degree with the mirror what is the angle of deviation between the incident ray and the reflected ray

Answer 1

50degree incident ray and 50degree reflected ray

Answer 2

heya ☺

it's too easy ,

angle of incident =50°

then angle of reflections=50°also (according to law of reflections)

And we also know that the sum of linear pair if 180°

so, angle of incident +angle of reflections +angle between the incident ray and reflected ray=180°

so,anle of deviation between the incident ray and reflected ray is=180°-100"°

=80°

hope it help you.
