Question

A sound source emits sounds of frequency 180 Hz that travel through still air at 340 m/s. The source moves away from the stationary listener at 75 m/s.

(a) Find the wavelength of the sound waves between the source and the listener.
  
(b) Find the frequency heard by the listener.
 
A sound source emits sounds of frequency 180 Hz that travel through still air at 340 m/s. The source moves away from the stationary listener at 75 m/s. ..(a).Find.the.wavelength of the sound waves between the source and the listener. EX m Enter a number. equency heard by the listener. Hz Because the sound waves in the region between the source and the listener will be spread out by the motion of the source, the frequency of the sound heard by the listener will be lower than the frequency emitted by the source.
