Step-by-step explanation:
A formula that is used to find the time period of a cyclic phenomena based on the frequency as follows :
[tex]T=\dfrac{1}{f}[/tex]
f is frequency
We need to solve the formula for f in terms of T. Cross multiplying the above formula such that :
[tex]T{\cdot} f=1\\\\f=\dfrac{1}{T}[/tex]
Therefore, this is the required explanation.
