Answer: D. 4167 Hertz

Step-by-step explanation:

We know that the formula to calculate frequency by using time period is given by :-

[tex]\nu= \dfrac{1}{T}[/tex], where T is the time period.

We are given that the time period of a musical note :

[tex]T=0.00024\text{ seconds}[/tex]

Then , the frequency of the musical note is given by :-

[tex]\nu= \dfrac{1}{0.00024}=4166.66666667\approx4167\text{ Hertz}[/tex]

Hence, the frequency of the musical note = 4167 Hertz
