Final answer:

The Doppler effect causes an increase in frequency when an observer moves toward a wave source.


Explanation:

If the observer moves toward the source at a constant speed, the observer will detect a steadily increasing frequency of the waves. This phenomenon is known as the Doppler effect, where motion relative to the source impacts the observed frequency: motion toward the source increases frequency, while motion away from the source decreases frequency.
