A violin string is .32m and has a mass of .0005kg. The freqency of the note played is 440Hz. What is the speed of the wave in the string?

.5*wavelenght = L
wavelength= 2*.32m
=.64m

v=f(wavelength)
=440hz*.64m
=281.6m/s

b) where must one put one's finger to play a note with a freqency of 494Hz?

v=f*wavelenght
281.6m/s=494Hz * wavelength
wavelength= .57m

Are these correct?
