Question

In case of sound, we can study the disturbance due to pressure wave and displacement wave. What is the phase difference between these two?

• A. 0.0
• B. $\pi$
• C. $\frac{\pi }{6}$
• D. $\frac{\pi }{2}$

Answer 1

The correct option is D $\frac{\pi }{2}$

Phase difference between the two waves i.e. pressure and sound is $\frac{\pi }{2}$
