What factors determine the frequency of a note emitted by a vibrating string?
Amplitude of vibration, force constant of string and length of string
Amplitude of vibration, force constant of string, and tension in string
Mass per unit length of string, tension in string and length of string
Force constant of string, tension in string, and length of string.
Vysvetlenie
The fundamental frequency of vibrations of a string is inversely proportional to the square root of mass per unit length (linear density),
if the tension and vibrating length of the string are constant.
