Question

When a ray of light strikes a plane mirror at an angle of ${15}^{\circ }$ with the mirror, what will be the angle of reflection with respect to the normal?

• A. ${15}^{\circ }$
• B. ${30}^{\circ }$
• C. ${75}^{\circ }$
• D. None of these

Answer 1

The correct option is C ${75}^{\circ }$

$\therefore \theta =({180}^o-{90}^o-{15}^o)={75}^o$
