The wavelength is twice the string length, or 0.62 m.
The frequency is 440 Hz.
The wave speed must be the product of the3 two, or 268.40 m/s.
Get the tension T from the formula
Wave speed = sqrt (T/5.84*10^-4 kg/m)
The tension will be in Newtons
The A string of a violin is 31 cm long between fixed points with a fundamental frequency of 440 Hz and a mass per unit length of 5.8×10^−4 kg/m.
What are the wave speed in the string?
What are the tension in the string?
What is the length of the tube of a simple wind instrument (say, an organ pipe) closed at one end whose fundamental is also 440 Hz if the speed of sound is 343 m/s in air?
What is the frequency of the first overtone of each instrument?
