Do displacement particle velocity and pr...

Do displacement particle velocity and pressure variation in a longitudinal wave vary with the same phase?

Text Solution

Verified by Experts

No the particle velcotu is `(pi)/(2)` out of phase with the displacement, and the pressure variation is out of phase by `pi` with the displacement.
