Doppler Effect of Sound Waves
 

Doppler Effect of Sound Waves problem 23


A source X emits a sound wave of constant frequency . The wave is subsequently received at a stationary detector Y. The frequency of the wave that is detected by Y is less than . What could be the reason for this?


  • Between X and Y, the wave undergoes diffraction.


  • Between X and Y, the wave undergoes reflection.


  • X is moving away from Y.


  • X is moving towards Y.
