A steel wire with mass 20.5 g and length 1.29 m is strung on a bass so that the distance from the nut to the bridge is 1.10 m.
(a) Compute the linear density of the string.
kg/m
(b) What velocity wave on the string will produce the desired fundamental frequency of the E1 string, 34.63 Hz?
m/s
(c) Calculate the tension required to obtain the proper frequency.
N
(d) Calculate the wavelength of the string's vibration.
m
(e) What is the wavelength of the sound produced in air? (Assume the speed of sound in air is 343 m/s.)
