What are the first three harmonics of a note produced on a 31.0 cm long violin string if waves on this string have a speed of 277.0 m/s?
Hz
Hz
Hz

frequency = (wave speed)/wavelength
The first harmonic has a wavelength of 2L = 62 cm.
The second harmonic has a wavelength of L = 31 cm.
The third harmonic has a wavelength of
(2/3)*L cm = 20.67 cm
