Main Question or Discussion Point
Could someone please concisely explain the difference between resonance and coherence?
Perhaps you could explain where you find the two terms indistinguishable. Coherence describes the spread in phases between a number of waves but resonance describes the phenomenon by which an oscillator can be excited by an incident wave or signal. They seem quite distinct, to me.Could someone please concisely explain the difference between resonance and coherence?
My problem with this is that you seem to be wanting to 'force' two words to be the same thing. The two terms are often used in connection with the same phenomenon, of course, but that's a different matter. Perhaps you have read about some phenomenon and what is written may have caused you to associate the terms more closely together than is normal. I think you need to read around and see how the two terms are used in general and that may resolve your apparent confusion.I apologize for my ignorance, as my understanding is quite limited, but isn't a harmonic oscillator tracing out a wave pattern in spacetime, so can't resonance be viewed as a wave interacting with an incident wave? Wouldn't there be interference and some degree of coherence/decoherence in such a system? Then wouldn't resonance be referring to coherent interference in spacetime?
