你需要知道的

In a transverse wave the vibrations are at right angles to the direction the wave travels.
In a longitudinal wave the vibrations are along the direction of travel, forming compressions and rarefactions.
Sound is longitudinal; ripples on water and light are transverse.
A wave carries energy from place to place, but the medium itself does not travel with it.
