Transverse V. Longitudinal V. Surface

Transverse Wave: The particle vibrates perpendicular to the direction of motion. An example of a transverse wave is a "wave" at a sporting event in which the audience rises from their seats and then sits back down again, creating the illusion of a wave.

A Transverse Wave

Longitudinal Wave: A longitudinal wave is a wave vibrating in the direction of propagation. An example of a longitudinal wave is a sound wave.

A Longitudinal Wave

Surface Wave: A surface wave is a wave in which two media are in contact. An example of a surface was is where air and water are in contact.

17.1 Vocabulary

Crest: The crest is the point on a wave in which the displacement is the highest.

Trough: A trough is the point on a wave in which the displacement is the lowest.

Amplitude: The amplitude is the maximum displacement or distance moved by a point on a wave.

Transverse Displacement: The transverse displacement is any point above or below the equilibrium.

Compression: Compression in a wave is the high pressure region in a wavelength.

Rarefaction: Rarefaction is the low pressure region in a wavelength.
