### Wave

travelling wavewavestraveling wave
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.
The types of waves most commonly studied in physics are mechanical and electromagnetic.

### Acoustics

Acoustics is the branch of physics that deals with the study of all mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound.

### Underwater acoustics

Underwater acoustics is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water, its contents and its boundaries.

In contrast, electromagnetic waves require no medium, but can still travel through one.

### Wavelength

One important property of mechanical waves is that their amplitudes are measured in an unusual way, displacement divided by (reduced) wavelength.

### Nonlinear system

### Transverse wave

There are three types of mechanical waves: transverse waves, longitudinal waves, and surface waves.

### Longitudinal wave

There are three types of mechanical waves: transverse waves, longitudinal waves, and surface waves.

### Surface wave

There are three types of mechanical waves: transverse waves, longitudinal waves, and surface waves.

To see an example, move an end of a Slinky (whose other end is fixed) to the left-and-right of the Slinky, as opposed to to-and-fro.

### Light

Light also has properties of a transverse wave, although it is an electromagnetic wave.

### Sound

Sound is a longitudinal wave.

### Interface (matter)

### Earthquake

Rayleigh waves have energy losses only in two dimensions and are hence more destructive in earthquakes than conventional bulk waves, such as P-waves and S-waves, which lose energy in all three directions.

The wave equation is an important second-order linear partial differential equation for the description of waves—as they occur in classical physics—such as mechanical waves (e.g. water waves, sound waves and seismic waves) or light waves.
