Question

Quizplus · Accepted Answer

If you run towards the source, the frequency you hear would be higher than F. This is called the Doppler effect, and it occurs because the relative motion between the source and listener results in a shift in the frequency of the sound waves. When you move towards a sound source, the waves are compressed, resulting in a higher perceived frequency.
