Question

The angle between the normal and the reflected ray is ${40}^0$. Find the angle of incidence.

• A. ${50}^0$
• B. ${20}^0$
• C. ${40}^0$
• D. Can't be predicted

Answer 1

The correct option is C ${40}^0$

The angle between normal and reflected ray is ${40}^0$
So, angle of reflection = ${40}^0$
And angle of incidence $=$angle of reflection$=$ ${40}^0$
