An airplane traveling at v = 163 m/s emits a sound of frequency 1730 Hz. At what frequency does a stationary listener hear the sound as the plane approaches? Use 340 m/s for the speed of the sound and answer in Hz.

1 answer

Fr = (Vs+Vr)/(Vs-Vp) * Fp
Fr = (340+0)/(340-163) * 1730 Hz = 3323
Hz. = Freq. heard by the receiver or
listener.
