In 2008, Adam Lopez set a world record by singing the highest note ever recorded, a C8. That is four octaves above middle C and not on a normal piano keyboard. What is the frequency to the nearest hertz of this musical note if its period is 0.00024?
A.
1,873 hertz
B.
2,631 hertz
C.
3,845 hertz
D.
4,167 hertz
The frequency (f) of a wave is the reciprocal of its period (T): f = 1/T. In this case, we can use the given period to find the frequency:
f = 1/0.00024 = 4166.7 ≈ 4167 Hz
Therefore, the answer is D. 4167 hertz.
