Question

Which of these diagrams correctly shows how a ray of light gets reflected?

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

According to law of reflection​:
Angle of incidence($i$) = Angle of reflection($r$)
$\Rightarrow \angle IOP=\angle POR$
Also, op is normal to the surface, so it will make ${90}^{\circ }$ with surface.
Hence, option d is only satuisfying these conditions.
