Q: If the frequency of a sound wave is 50 hertz, find its time period.
  • A. 0.05 second
  • B. 0.02 second
  • C. 0.5 second
  • D. 0.2 second
Correct Answer: Option B - Frequency (f) = 50 hertz Time period (T) =? Time period (T) = 1 / f = 1/50 = 0.02 second.
B. Frequency (f) = 50 hertz Time period (T) =? Time period (T) = 1 / f = 1/50 = 0.02 second.

Explanations:

Frequency (f) = 50 hertz Time period (T) =? Time period (T) = 1 / f = 1/50 = 0.02 second.
