A cavity is a hole. It may refer to:
- Dental cavityDental cariesDental caries, also known as tooth decay or a cavity, is an irreversible infection usually bacterial in origin that causes demineralization of the hard tissues and destruction of the organic matter of the tooth, usually by production of acid by hydrolysis of the food debris accumulated on the...
, damage to the structure of teeth - Body cavityBody cavityBy the broadest definition, a body cavity is any fluid-filled space in a multicellular organism. However, the term usually refers to the space located between an animal’s outer covering and the outer lining of the gut cavity, where internal organs develop...
, a fluid filled space in many animals where organs typically develop - Cavity wallCavity wallCavity walls consist of two 'skins' separated by a hollow space . The skins are commonly masonry such as brick or concrete block. Masonry is an absorbent material, and therefore will slowly draw rainwater or even humidity into the wall. The cavity serves as a way to drain this water back out...
, a wall consisting of two skins with a cavity. - ResonatorResonatorA resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonant frequencies, with greater amplitude than at others. The oscillations in a resonator can be either electromagnetic or mechanical...
, a device designed to select for waves of particular wavelengths- Optical cavityOptical cavityAn optical cavity or optical resonator is an arrangement of mirrors that forms a standing wave cavity resonator for light waves. Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser light. They are also used in optical parametric...
, the cavity resonator of a laser
- Optical cavity
- CavitationCavitationCavitation is the formation and then immediate implosion of cavities in a liquidi.e. small liquid-free zones that are the consequence of forces acting upon the liquid...
, the phenomenon of partial vacuums forming in fluid, for example, in propellors - Cavitary pneumoniaCavitary pneumoniaCavitary Pneumonia is a disease in which the normal lung architecture is replaced by a cavity. In the healthy lung, oxygen transport occurs at the level of the alveoli which has an average size of 0.1 mm...
, a type of pneumonia in which a hole is formed in the lung - Cavity (band)Cavity (band)Cavity was an American sludge metal band from Miami, Florida. They formed in 1992 and broke up around 2003. Steve Brooks and Juan Montoya would go on to play in Torche and Floor...
