What is the difference between a transverse wave and a longitudinal wave?

• longitudinal wave vibrates the medium at right angles & transverse waves vibrates the medium in the same direction
• transverse wave vibrates the medium at right angles & longitudinal waves vibrates the medium in the same direction
• there is no difference
• one is above the surface and the other is below
