Resonance/ Natural Resonance Frequencies?
I am doing a small physics research project introducing sound, resonance, and natural resonance frequencies, but I have questions.
I know that resonance is the tendency of a system to oscillate with larger amplitudes at some frequencies rather than others. Does this just mean that the object is mor sensitive to certain vibrations i.e, its natural resonance frequencies?
And this statement is justified by the fact that matter stores a certain amount of vibrational energy which makes it sensitive. Is this stored vibrational energy due to the atoms that make up the matter involved? or what?
Are objects always vibrating, then? Are they constantly vibrating at a pace of their own natural resonance frequency?
Why will resonance not occur if the two frequencies do not match?
Re: Resonance/ Natural Resonance Frequencies?
Every solid body has a stiffness(resistance to deformation), can be approximated by a mass-spring-damper system, will have a resonant frequency. Resonance will occur if the external driving frequency matches the resonant frequency(or multiples of it/harmonics) of the body.
