Resonator Resonator A 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 (including acoustic). Resonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal. Musical instruments use acoustic resonators that produce sound waves of specific tones. Another example is quartz crystals used in electronic devices such as radio transmitters and quartz watches to produce oscillations of very precise frequency. A cavity
Baptism for the dead something that Marcion denied, and that, in fact, "baptized for the dead" means baptized for the body destined to die and rise again. Somewhat similarly, John Chrysostom explained Paul's mention of people being "baptized for the dead" as a reference to the profession of faith they made in their own future resurrection before being baptized. Some interpret "baptized for the dead" as a metaphor for martyrdom, as in and baptism is a metaphor for suffering or martyrdom; accordingly they would translate it as "being baptized with a view to death". In this interpretation, the phrase is closely linked with what
