How does the transfer of energy occur at resonance?

Just as with telling jokes, timing is all important when transferring energy from one oscillator to another. If you randomly push a swing you will be pushing with it some of the time and against it at other times. The net effect is zero! read more

That is exactly what is happening when two oscillators transfer energy between each other. If they are in step then we get resonance but if their frequencies are not nearly the same then no resonance can happen because the change to one caused by the other has different effects at different times. read more

Förster resonance energy transfer (FRET), fluorescence resonance energy transfer (FRET), resonance energy transfer (RET) or electronic energy transfer (EET) is a mechanism describing energy transfer between two light-sensitive molecules (chromophores). read more

One is velocity resonance – the speed of the driveN system is a maximum and this occurs at the natural frequency of the undamped driven system whether or not there is damping. This is also true of energy resonance which is characterised by maximum power (energy/time) being transferred from the driveR to the driveN. read more
