Question

The frequency of the musical note F3 is 1.85 102 hertz. What is its period?

A 5.40 x 10-3seconds
B. 1.05 x 10-3 seconds
C. 3.09 x 10-3 seconds
D. 5.31 x 10-1 seconds

Answer 1

Answer: 0.0054 s

Explanation: There is an inverse relation between the frequency and the period of a wave (a sound wave in this case):

T=1/F

Where f = 1.85 (10)² H z

Hence : T = 1/1.85 (10)² H z T =0.0054s
