The wave velocity of a transverse wave on a string of length 0.500 m is 225 m s−1 .
(1) Determine the frequency of the first harmonic of a standing wave on this string when both ends are kept fixed.
(2) Calculate the wavelength of the sound produced in air by the oscillating string in part a. (Take the speed of sound in air to be 340 m s−1 .)
