Question

If the angle of incidence of sound wave is ${30}^{\circ }$, what is the angle of reflection?

• A. ${40}^{\circ }$
• B. ${50}^{\circ }$
• C. ${30}^{\circ }$
• D. ${20}^{\circ }$

Answer 1

The correct option is C ${30}^{\circ }$

We know for a sound wave,
Angle of incidence = Angle of reflection
Given, angle of incidence $={30}^{\circ }$.
Therefore, angle of reflection $={30}^{\circ }$.
