A string fixed at both ends is 9.31 m long and has a mass of 0.125 kg. It is subjected to a tension of 100.0 N and set oscillating.
(a) What is the speed of the waves on the string?
m/s

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

(c) Give the frequency of that wave.
Hz

• Physics -

wave velocity=sqrt (tension/(mass/length)

longest wavelength: 1/2 Lambda = 9.31 m long

frequency=speedofwave/wevelength

• Physics -
