Specifically as to the validity of CoR as a metric for the bounciness of an object. CoR is inherently a property of /two/ objects, say, the interaction between rubber and steel. Is it truly the case that given two objects, it's impossible to say that one object is bouncier than another? This is...
That makes some sense, but I'm still a little confused... Say I have the following closed pipe resonating at it's first harmonic:
_______________..D
|A.....B...C
|A.....B...C
|A____________B...C
......D
Then, as I understand it, the air particles at points A aren't moving...
This being WRT resonating pipes. Apparently the acoustical length of the pipe is different to the physical length due to the vibration of the sound particles moving the particles at the opening so that the physical length is no longer the length of resonance.
I've found many sources on the...
