Vacuum

Transverse Wave -perpendicular to the source.

Mechanical wave - vibrates the
medium (moves stuff)

E.M. waves - does NOT move
stuff

Longitudinal Wave - moves in the same direction as the vibration.

Rarefaction - where the longitudinal wave stretches.
Compression - where the longitudinal wave shrinks

-A particle on the wave tend to travel in a circular
motion.
