Some waves move through matter. The matter that a wave moves through is called the of the wave. A traveling wave is a disturbance that moves through space and time, transferring without transferring matter. Waves originate from an initial disturbance, or , that provides some energy to the system. In general, as particles in a medium oscillate or vibrate, they the energy of this oscillation to particles around them, and this process continues to transmit the energy of an oscillation to particles across a distance. Through this process, a wave “ ” through a medium. In this way, waves transfer energy without transferring matter. When particles oscillate in a direction to the direction that the wave propagates, the wave is a wave. This is the most familiar type of wave. However, sometimes the particles in a wave oscillate in the direction that the wave propagates. These waves are called waves. Sound waves and seismic “P-waves” are examples of longitudinal waves. They are occasionally known as waves or compression waves.

Figure A represents a wave, in which matter oscillates to the direction of wave propagation. Figure B represents a wave, in which matter oscillates to the direction of wave propagation. In both cases, energy is transmitted parallel to the direction of wave propagation.

Similar to the wavelength is the wave period (or just “period”) of a wave. The wave period is the it takes for a wave to complete one full . The period is a measure in “ ,” so it is expressed in units of seconds and is represented by the symbol .

Imagine a string, that, at rest as an amplitude of 0 on the y-axis and therefore looks like a straight line in its equilibrium position (x-axis). When it is moved up and down, it gains energy and oscillates back and forth about the point (x-axis). When plotted over time, we get the graph of a wave.

The inverse of the period, that is to say, the number of oscillations that a wave makes in one second, is referred to as the of a wave. It is measured in " per second", which has units of 1/s. This unit is referred to as . The symbol "f" is often used to denote frequency.

Compressional seismic waves generated by earthquakes that travel through Earth (can travel through liquids, gases and solids) are known as waves.

waves are a type of seismic wave that propagates only through solids; a transverse wave.

The boundaries outside of which seismic waves are not recorded due to the liquid core stopping or refracting various waves is known as a zone.

waves are seismic waves that don't travel through Earth's interior and tend to be the most destructive due to their low frequency, long duration and large amplitude.
