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.
I will be happy to critique your thinking. on part b, use the wave equation.
