39. A violin string 17.8 cm long and fixed at both ends oscillates in it's n = 5 mode. The speed of waves on the string is 206 m/s, and the speed of sound in air is 348 m/s. What are (a) the frequency and (b) the wavelength of the emitted sound wave?

51. The A string of a violin is a little too tightly stretched. Beats at 4 per second are heard when the string is sounded together with a tuning fork that is oscillating accurately at concert A (440 Hz). What is the period of the violin string oscillation?
