QUESTION:

A light ray STRIKES the surface of plane mirror at an angle 40° with the surface of mirror. What is the angle of reflection?

ANSWER:

Angle of reflection = \bold{\angle r = 50°}

Point to remember:

\sf{\bullet \:Angle\:of\:incidence=Angle\:of\:reflection}

Solution:

\sf{\purple{Angle\:of\:incidence=90° - 40°}}(angle with mirror)

\bold{\purple{Angle\:of\:incidence=50°}}

\sf{\red{Angle\:of\:incidence=Angle\:of\:reflection}}

\bold{\red{Angle\:of\:reflection=50°}}
