The frequency that the listener will hear is2000 Hz.

when the source is stationary and the listener moves towardthe source at one-half the speed of sound, the frequency that thelistener hear became 1500 Hz.

Explain on physical grounds why thetwo frequencies differ.

- physics pls help -

on physical grounds", but it can be shown mathematically why the difference

exist.
