What is Resonator?
A '''resonator''' is something that [[resonate]]s. This may make a particular [[frequency]] of a sound or other [[vibration]] become bigger. ==Electromagnetics== {{Electromagnetism}} In electromagnetics a '''cavity resonator''' is a resonator composed of a space that is usually surrounded by a [[dielectric]] or [[metal]] which allows standing wave patterns at particular frequencies, [[eigenmodes]], correlated to their size, shape, and material. ==Music== Most [[musical instrument]]s have resonators. They are the parts which makes the sound louder. A [[vibraphone]], for example, has long tubes underneath the keys. It also has a special effect: a mechanism which, when it is turned on, opens and shuts the resonators very quickly so that a trembling sound is heard. The body of a [[violin]] is a resonator: without the body the sound of the string vibrating would hardly be heard, just as the sound of an [[elastic band]] stretched between two [[finger]]s can hardly be heard. {{music-stub}} [[Category:Musical instrument construction]] [[Category:Physics]]
