A transverse representation of a longitudinal wave is shown at the bottom of the figure. Here vertical lines are drawn through the rest positions (indicated by a,b,c, etc.), with lengths proportional to the distances that the masses have moved from equilibrium (their amplitudes).

Sound Waves in Air. A single-frequency sound wave traveling through air will cause a sinusoidal pressure variation in the air. The air motion which accompanies the passage of the sound wave will be back and forth in the direction of the propagation of the sound, a characteristic of longitudinal waves.


118
Transverse Waves. A transverse wave is a wave in which the motion of the medium is a right angles to the direction of the wave.


745
A transverse wave is a moving wave that consists of oscillations occurring perpendicular (right angled) to the direction of energy transfer (or the propagation of the wave).

Earthquakes and other geologic disturbances sometimes result in the formation of seismic waves. Seismic waves are waves of energy that are transported through the earth and over its surface by means of both transverse and longitudinal waves.

Transverse wave: Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.

In the first part of Lesson 1, it was mentioned that sound is a mechanical wave that is created by a vibrating object. The vibrations of the object set particles in the surrounding medium in vibrational motion, thus transporting energy through the medium.


523
Sound can propagate through a medium such as air, water and solids as longitudinal waves and also as a transverse wave in solids (see Longitudinal and transverse waves, below).

There are two types of wave motion: transverse and longitudinal.You need to learn these names, and what distinguishes them. Transverse is the one most people can draw. The oscillations are at 90° to the wave motio

Ocean waves and sound waves are really similar: They've got troughs and crests, and frequencies and interferences, but did you know earthquakes travel in waves, too?
