Observed frequency versus time for the rotating sound source.
Observed frequency versus time for the rotating sound source.
A sound source mounted on the outer edge of a rotating horizontal carousel emits sound of constant frequency. A stationary spectator located far away in the plane of rotation records the observed frequency \(f\) of the sound as a function of time \(t\), as shown in the graph. The speed of sound in air is \(340 \text{ m/s}\). What is the approximate radius \(R\) of the carousel?
