A wooden platform can be rotated about its vertical axis with constant angular speed `omega` with the help of a motor. A buzzer is fixed at the circumference of the platform and it rotates in a circle of radius R. The buzzer produces sound of frequency `f_(0)`. A mic is placed just beneath the platform near its circumference. An electronic frequency analyzer connected to the mic records the frequency `(f)` received by the mic. Take time `(t)` to be zero when the buzzer is just above the mic and express `f` as a function of time. Plot f versus t. Speed of sound `= V_(0)`.
