a violin string vibrates at 196 Hz. what frequency will it vibrate with if it is fingered at one quarter of its length.
if the wavelength of the string unfingered is λ, what will it be in the scenario you describe? Use the answer to that question together with the fact that (wavelength) x (frequency) = speed, which is a constant λf=v
theres only 1 number given to us in this question, how do you find speed when all we have is frequency ?
