Longitudinal Waves

In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. The animation below shows a one-dimensional longitudinal plane wave propagating (moving) down a tube. The particles do not move down the tube with the wave; they simply oscillate back and forth about their individual equilibrium positions. Pick a single particle and watch its motion. The wave is seen as the motion of the compressed region (ie, it is a pressure wave), which moves from left to right.

The second animation below shows the difference between the oscillatory (back-and-forth) motion of individual particles and the propagation (movement) of the wave through the medium. The animation also identifies the regions of compression and rarefaction.

Look at the animations of longitudinal waves above. What happens to the particles of matter (red dot) as the waves move through them?

They travel down the screen with the wave and do not come back to their original position.

They move side to side, but come back to their original position.

They move up and down, but come back to their original position.

They do not move at all.

In a longitudinal wave the particles move ______________________ to the direction of the wave.

Perpendicular (across the wave's direction)

Parallel (in the same direction)

Transverse Waves

In a transverse wave the particle displacement is perpendicular to the direction of wave propagation. The animation below shows a one-dimensional transverse plane wave propagating from left to right. The particles do not move along with the wave; they simply oscillate (move) up and down about their individual equilibrium positions as the wave passes by. Pick a single particle and watch its motion.

Look at the animation of the transverse wave above. how would a human sitting in an intertube move?

They travel down the screen with the wave and do not come back to their original position.

They do not move at all.

They move up and down, but come back to their original position.

They move side to side, but come back to their original position.

In a transverse wave the particles move ______________________ to the direction of the wave.

Parallel (in the same direction)

Perpendicular (opposite)

Water Waves

Water waves are an example of waves that involve a combination of both longitudinal and transverse motions. As a wave travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases. The animation at right shows a water wave travelling from left to right in a region where the depth of the water is greater than the wavelength of the waves. I have identified two particles in orange to show that each particle indeed travels in a clockwise circle as the wave passes.
