A string fixed at both ends is 8.71 m long and has a mass of 0.119 kg. It is subjected to a tension of 92.0 N and set oscillating.

(a) What is the speed of the waves on the string?

(b) What is the longest possible wavelength for a standing wave?

(c) Give the frequency of that wave.

(a) V = sqrt (T/d)
T = 92 N
d = lineal density (mass divided by length)

(b) Twice the string length

(c) V/(wavelength)
