The period of the musical note is
seconds.
Answer: Option A
<u>Explanation:</u>
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.
