Question

When a ray of light falls normally on the mirror, then the angle of reflection will be

• A. ${90}^{\circ }$
• B. ${120}^{\circ }$
• C. $0^{\circ }$
• D. ${30}^{\circ }$

Answer 1

The correct option is C $0^{\circ }$

Angle of incident for a normal ray is $0^{\circ }$
As $\text{angle of reflection = Angle of incident}$
So, Angle of reflection $=0^{\circ }$
