Can longitudinal wave be polarised

Answer 1

No, the longitudinal wave can't be polarised. Because polarisation means lack of symmetry. But longitudinal waves are symmetrical from all the sides of vision. This is because their plane of propagation and vibration is same. this wave loks same from all the sides.

Answer 2

No, longitudinal waves cannot be polarized because they oscillate in the same direction as their propagation, making it impossible to filter out the perpendicular components to achieve polarization. Examples of longitudinal waves include sound waves in air.
