Waves

TransverseWaves!

Longitudinal waves include sound waves and seismic P-Waves.

A surface wave is a seismic wave that is trapped near the surface of the earth.

A surface wave is a mechanical wave that propagates along the interface between differing media, usually two fluids with different densities.

A transverse wave is a moving wave that consists of oscillations occuring perpendicular to the direction of energy transfer.

All mechanical waves have to travel through something which is called a medium. For example, if a mecanical wave moves through the air, then air is the medium. Inside the medium are particles displaced by the wave.(click for more)

They are waves that oscillate back and forth on an axis that is the same as the axis along which the wave propagates. Sound waves are longitudinal waves, since the air molecules are displaced forward and backward on the same axis along which the sound travels.

The amplitude of a wave is a measure of its size, or the distance between its peak and trough. It is also a measure of the amount of energy in a wave. While amplitude is haerd to calculate for longitudinal wabes, it is fairly simple task to calculate in transverse waves.

Ultrasound is an oscillating sound pressure wave with a frequency greater than the upper limit of the human hearing range.
