Infra-red spectroscopy...
I have been taught that with Infra-red spectroscopy, when different infrared wavelengths are fired at the sample when we reach the correct frequency we can cause the atoms in the bond to resonate as they absorb the correct energy. My question is why does it have to do with energy? After all, let's take the example of a swing and talk about resonance - you have to push the swing with the correct frquency to cause it to resonate; it does not matter how much energy you supply as this will only make it resonate more. So why do we talk about the correct energy of the infra red light rather than the frequency at which a force or energy is supplied?
Thanks in advance.
