2. which of the following statements incorrectly describes a scenario where the source of the sound wavesand the person hearing the sound are remaining stationary? the frequency of the sound waves is not affected by the nature of the medium. b. the frequency of the sound waves will remain the same to the listenerc. the frequency of the sound waves is not altering as a result of the distance between the sound source and the listenerd. the frequency of the sound waves will change for the listener as a result of the doppler effect.

The question is asking for which statement is WRONG:

A).,  B).,  and  C).  all say the same thing in screwy different ways.
If the source and the observer are not moving, then the observer hears
sound with a steady frequency that doesn't change, and it doesn't depend
on the medium ... it's the same frequency that the source is putting out.
That's true, so none of these is the answer.

D).  No.  Incorrect.  Honk.  Bleep.  Wrong.
If the source and the observer aren't moving,
then there's no Doppler effect.

This is the answer.  (Looking for the FALSE statement.)
