The frequency of the musical note f#3 is 1.85x102 hertz. what is its period?

a. 5.40x10^-3 seconds
b. 1.05x10^-3 seconds
c. 3.09x10^-3 seconds
d. 5.31x10^-1 seconds

The period of the musical note is seconds.

Option A

Explanation:

The frequency is defined as the number of oscillations or a complete cycle of wave occurred in a given time interval. So the frequency is inversely proportional to the time period. Thus the mathematical representation of frequency with time period is

As the frequency is given as , the time period can be found as

Thus,

Thus the time period for the frequency of the musical note is seconds.
