Here it is shown that the superposition of a transverse damped inhomogeneous wave and of a longitudinal wave is also a solution, in the case when the propagation direction of the longitudinal wave is orthogonal to the polarization direction of the transverse wave.

Can interference occur in longitudinal waves?

Diffraction and interference effects occur for both longitudinal and transverse waves, and so cannot be used to distinguish between these types.

Can longitudinal waves be stationary?

Both longitudinal (e.g., sound) waves and transverse (e.g., water) waves can form standing waves. This section focuses on waves in bounded mediums—in particular, standing waves in such systems as stretched...
