Question

If the angle of incidence is ${80}^o$, what will be the angle of reflection with respect to the normal drawn perpendicular at the point of reflection ?

• A. ${80}^o$
• B. ${100}^o$
• C. ${160}^o$
• D. ${20}^o$

Answer 1

The correct option is A ${80}^o$

From laws of reflection, we get angle of incidence $i$ is equal to the angle of reflection $r$.

Angle of incidence $i={80}^o$

Thus angle of reflection $r=i={80}^o$
