1. The problem statement, all variables and given/known data
When an instrument plays a note, the resulting sound is a combination of all the possible harmonics for that instrument in its momentary configuration. For instance, a musician changes notes on a violin by pressing the strings against the neck of the instrument, thus shortening the string length and changing the possible harmonics. A given shortened string will play at one time all the possible harmonics allowable by its string length. A given note is the same set of harmonics for all instruments.
1. Doesn't a wavelength have an infinite possibility of harmonics?
2. Why is there no beat frequency if each harmonic has a different frequency.
These aren't actual questions from my study books but they are really confusing to me.
2. Relevant equations
1. f=nv/2L
2. beat frequency= abs (f1=f2)
3. The attempt at a solution
1. My reasoning for thinking that there is an infinite number of possible harmonics is that you can keep increasing n in f=nv/2L.
2. Maybe there is no beat frequency because the frequencies are not close enough together or maybe the fundamental frequency "envelopes" the rest of the harmonic frequencies?
