At a swimming pool, a music fan up on a diving platform is
listening to a radio. As the radio is playing a tone that has a
constant frequency fs, it is accidentally
knocked off the platform. Describe the Doppler effect heard by (a)
the person on the platform and (b) a person down below in the
water. In each case, state whether the observed frequency
f0 is greater or smaller than
fs.
(a) the observed frequency is smaller (b) the observed
frequency is greater |
