3. The number of complete cycles in a given period of time is the
of a periodic motion.
Wavelength (page 505)
4. The distance between a point on one wave and the same point on the
next cycle of the wave is called . Circle the correct
answer.
frequency period wavelength

Answer 1

1. True — a periodic motion repeats at regular time intervals.

2. period — the time required for one complete cycle.

3. frequency — the number of complete cycles in a given time.

4. wavelength — the distance between a point on one wave and the same point on the next cycle.
