Waves

Transverse waves are waves which the particle vibrates in an up-and-down motion. Longitudinal waves are waves in which the particles of the medium vibrate parallel to the direction of the wave motion. These waves are similar because pushing a spring back and forth creates a longitudinal wave, much the same way that shaking a rope up and down creates a transverse wave.

A crest is the highest point of a transverse wave, and a trough is the lowest point of a transverse wave. Their similar because their both related to transverse waves. A medium is a substance through which a wave can travel. A wave is any disturbance that transmit energy through matter or empty space. A rarefaction is like the crests and troughs of a transverse wave. Also, a compression is a part of a longitudinal wave where the particles are crowded together.
