Question

A light ray makes an angle of incidence ${60}^o$, when it falls on a plane reflecting sheet. The angle of reflection will be :

• A. ${60}^o$
• B. ${30}^o$
• C. ${45}^o$
• D. ${90}^o$

Answer 1

The correct option is A ${60}^o$

Given $\angle i={60}^o$
From laws of reflection, $\angle i=\angle r={60}^o$
