Test to distinguish between transverse and longitudinal waves?Watch
Which physics test is used to distinguish between longitudinal and transverse waves?
Perhaps that you can polarise transverse waves but not longitudinal?
Transverse waves have wave vibrations at right angles (perpendicular) to the direction of travel, and longitudnal waves have vibrations along the direction of travel.
Examples of transverse waves are all electromagnetic waves, and an example of a longitudinal wave is sound
