Categories of Waves Waves come in many shapes and forms. While all waves share some basic characteristic properties and behaviors, some waves can be distinguished from others based on some observable and some non-observable characteristics.
It is common to categorize waves based on these distinguishing characteristics. Longitudinal versus Transverse Waves versus Surface Waves One way to categorize waves is on the basis of the direction of movement of the individual particles of the medium relative to the direction that the waves travel.
Categorizing waves on this basis leads to three notable categories: A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.
Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil up and down. Energy will begin to be transported through the slinky from left to right.
As the energy is transported from left to right, the individual coils of the medium will be displaced upwards and downwards. In this case, the particles of the medium move perpendicular to the direction that the pulse moves. This type of wave is a transverse wave. Transverse waves are always characterized by particle motion being perpendicular to wave motion.
A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil left and right.
As the energy is transported from left to right, the individual coils of the medium will be displaced leftwards and rightwards.
In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion. A sound wave traveling through air is a classic example of a longitudinal wave.
As a sound wave moves from the lips of a speaker to the ear of a listener, particles of air vibrate back and forth in the same direction and the opposite direction of energy transport. Each individual particle pushes on its neighboring particle so as to push it forward. The collision of particle 1 with its neighbor serves to restore particle 1 to its original position and displace particle 2 in a forward direction.
This back and forth motion of particles in the direction of energy transport creates regions within the medium where the particles are pressed together and other regions where the particles are spread apart.
Longitudinal waves can always be quickly identified by the presence of such regions.
This process continues along the chain of particles until the sound wave reaches the ear of the listener.Wave propagation is the physics term for the movement of waves. Today we're going to discuss the various ways that waves of different types can move and how those are different from each other.

The website contains written and oral history, dimensions, photographs, and documents about these popular boats. 7.
RADIO WAVE PROPAGATION The propagation of radio waves through space (and the atmosphere) is the essential phenomenon exploited by a radio communications system.
As described earlier (sec. 3), this phenomenon has been studied extensively using . In the transverse or shear wave, the particles oscillate at a right angle or transverse to the direction of propagation.
Shear waves require an acoustically solid material for effective propagation, and therefore, are not effectively propagated in materials such as liquids or gasses. Mar 11, · A second version of this dataset combines the Wave Propagation model with the other Japan Tsunami datasets that are available here.
It starts by showing the earthquake activity leading up to the tsunami, then shows the tsunami wave propagation combined with earthquake activity and then ends with a map of maximum wave heights. Wave propagation: Waveguides. © Amanogawa, - All Rights Reserved - All Rights Reserved.
