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

The answer to this question is C.  The reason why this is an incorrect statement is that the Doppler effect takes into account two moving objects.  In this scenario, both the source and the listener are stationary to the frequency of the sound waves will not change due to the Doppler effect.  For the other answers, the frequency of sound waves is not affected by nature of the medium.  The distance between a sound source and listener does not alter the frequency of the sound wave.  The frequency of the sounds waves remains the same to the listener.
