Problem
A stretched violin string of length 0.65 m emits its third harmonic at 600 Hz when the violin is at rest. The violin is then placed on a trolley moving towards a stationary observer at 5 m s⁻¹. If the observer simultaneously sounds a tuning fork of 600 Hz, determine the beat frequency heard. (Speed of sound in air = 330 m s⁻¹.)
