Ganymede, Europa and Io participate in a 1:2:4 form of the (*) orbital version of this phenomenon.
In systems which exhibit this phenomenon, one quantity is given by 2 pi times this phenomenon's namesake frequency times the energy stored divided by power lost. That quantity is the Q factor. Microwaves are used to excite electrons in an external magnetic field from lower- to higher-energy spin states in a form of spectroscopy called electron spin this. In an LC circuit, a quantity named for this phenomenon is given by 1 over the square root of inductance times capacitance. Ganymede, Europa and Io participate in a 1:2:4 form of the (*) orbital version of this phenomenon. A form of this phenomenon induced by vortex shedding is often erroneously implicated in the collapse of the Tacoma Narrows Bridge. For 10 points, name this phenomenon in which the amplitude of an oscillating system is maximized at its namesake frequency.
