Wave Vocabulary Practice

Transverse Waves Vocabulary in Action

This is the crest of a transverse wave. The crest is the tallest part of a transverse wave.

This is the trough of a transverse wave. The trough is lowest part of a transverse wave.

This is the wavelength of a transverse wave. The wavelength is the distance between two (2) crests or two (2) troughs. This image shows the wavelength between two crests.

This is the amplitude of a transverse wave. The amplitude is the height of the resting place and a crest or a trough. This image shows the amplitude to the crest of the wave.

Longitudinal Waves Vocabulary in Action

These are compressions in a longitudinal wave. Compressions in a longitudinal wave are where the particles in the medium are closest together.

These are rarefactions in a longitudinal wave. Rarefactions in a longitudinal wave are where the particles are furthest apart in a medium.
