resonance frequency! what is meant by resonance frequency ? i really can't get it. if anyone could help i will be gratefull.

would it be more accurate to say that Resonance is Essential for musical instruments or Desirable.

Why does an oscillating system under resonance oscillate with the largest amplitude? And why does resonance occur when the driving frequency match the natural frequency? Can resonance occur at frequency other than natural frequency?

A guitar string resonates at 1260 Hz and 1575 Hz with no resonance frequencies in between. Find its fundamental(the lowest) resonance frequency. I know that fundamental frequency is the number of times it completes in one second, measured in hertz. In this specific problem, should I be...

I know that when the applied frequency on a mass is equal to the natural frequency, the mass resonates. It has a great amplitude as a result of this. But I don't know how somethings affect the resonant frequency. Like for a mass-spring system. 1) What effect would increasing the mass have...

Hi, I'm confused by resonance structures of molecules, what are they really? My teacher said resonance structures are in fact a decomposition of the actual molecular wave-function as a sum of simpler ones. Is this true? Or are they in fact simply pictures we draw when we can not classify the...

Just a qns, how does resonance work? i know about the natural frequency stuff, but why and how does it occur? why in the 1st place do every object has a natural frequency and different natural freq. And by the way, if we know the natural frequency of a man, couldn't we potentially can kill...

I'm reading a few papers on resonant captures, and I come across the terms strong resonance and weak resonance, without actually seeing them defined. I've got my guesses. I think 3:2 and 2:1 are considered strong, and I believe that it's because objects in 3:2 and 2:1 will complete a...
