Question

two plane mirrors are inclined to each other at some angle .a ray of light is incident on one of them at an angle of 35 degree .The light after reflection falls on second mirror and gets reversed.find the angle between the mirror?

Answer 1

angle of incidence=35


angle of reflection=angle of incidence

angle of reflection=35

angle between mirror and reflected ray are complementary

angle between mirror +35=90

angle between mirror =90-35

angle between mirror 55
