Answer:
Frequency
Explanation:
A period is the number of revolutions in a minute.
[tex] Period = \frac {time}{number \; of \; oscillations}[/tex]
Also, frequency can be defined as number of oscillation per unit time.
Mathematically, frequency is given by the formula;
[tex] Frequency = \frac {number \; of \; oscillations}{time}[/tex]
Thus, we can deduce that frequency of an oscillation is the inverse of the period (time) of oscillation.
Mathematically, period is expressed as;
[tex] Period = \frac {1}{frequency}[/tex]
This ultimately implies that, an object's period of oscillation can always be used to solve for frequency.
