The principles of resonance are such that the greatest amplitude of a vibrational or electrical wave peak at a certain frequency, and they peak while consuming less power overall to maintain it.
I'm wondering, since an electron has a resonant frequency, and so does a system of water molecules, brick, person, and planet; how would an incoming vibrational wave of infinite 'Q' (so basically it has a very accurate and narrow bandwidth resonant frequency) tell the difference between two objects of the same resonant frequency?
So if you have an apple that resonates at 10.8Hz, and an apple that resonates at 10.3Hz, and your incoming wave is at 10.8Hz with infinite Q, obviously all of the power goes to the first apple, and it peaks.
But if you have an 11Hz apple and an 11Hz pear, (two different objects), what happens?
I would think that if you had two identical apples at 11Hz, it would split the power between them such that the new amplitude is some lesser exponential than it would have been if there was only one apple at 11Hz.
What if the wave is not vibrational, but electromagnetic, same thing right?
