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.




1

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

1

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

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.



1

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

1

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

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.

1

Look at the animation of the water wave above. If you were on a surf board in the ocean, how would you move in relation to the wave?

1

If the frequency of a wave is increased, what will happen to the wavelength?

1

On a longitudinal wave, in which areas are particles farthest apart?
