Why can't longitudinal waves be polarised by transverse waves can?
particles vibrate in same direction wave travels thus cannot be polarised

Polarisation confines the vibrations to a single plane (at 90 degrees to the direction of energy transfer).
Because the vibrations in a longitudinal wave are parallel to the direction of energy transfer, we cannot confine them to a single plain.
For exams, Im pretty sure its enough to just say that the vibrations are parallel to the direction of energy transfer, thus it is not possible to confine the vibrations.
