a tuning fork of frequency 500 Hz is rotating on the edge of a disk of radius 1.2 meters. (a) If the disk turns at a rate of 40 rev/min, what are the maximum and minimum frequencies heard by the listener? (b) To what positions of the tuning fork do these frequencies correspond?
max velocity toward the listener occur on the opposite sides.

then use the doppler equation
