Question

When an automobile moves towards a listener, the sound of its horn seems relatively

a. Low pitched (low frequency) b. High Pitched (high frequency)
c. Normal (no change in frequency)

Higher Pitched! (b)

Step-by-step explanation:

The Doppler effect makes it seem high pitched, as the sound waves are mushed together at a higher frequency, while moving away, the sound waves spread out like a lower frequency wave!
