If a 1.00kHz sound source moves at a speed of 50.0m/s toward a listener who moves at a speed of 30.0m/s in a direction away from the source, what is the apparent frequency heard by the listener? The speed of sound in air is 343m/s.
Applying the formula for the Doppler effect, obtain the observed frequency:
where is the speed of soung, is the speed of the listener, is the speed of the source, and is the natural frequency of the source. Thus, find
Answer. 1.068 kHz.
