If a string is 1.6 meters long and it vibrates in the first and second harmonics, determine the wavelength for each pattern.

Question

If a string is 1.6 meters long and it vibrates in the first and second harmonics, determine the wavelength for each pattern.

Answer 1

Length of string = 1.6 m

If the entire length has one full loop , Then wave length = 0.8 m ( fundamental frequency)

for second harmonic frequency is double and hence wavelength is half = 0.4 m
