Answer:
Frequency
Step-by-step explanation:
A periodic oscillation can be described by using different quantities. The most important are:
- Amplitude: the maximum displacement of the oscillation, relative to its equilibrium position
- Period: the time it takes for the system to complete one full oscillation
- Frequency: the number of complete cycles the oscillation makes per second
From the definitions above, we see that the quantity that the problem is asking for is the frequency. Frequency is also related to the period by the equation
where T is the period of oscillation.
