Question

A sound wave has a frequency of $ 440 \, \text{Hz} $. What is its time period?

• A. \( 0.00227 \, \text{s} \)
• B. \( 0.002 \, \text{s} \)
• C. \( 0.0025 \, \text{s} \)
• D. \( 0.004 \, \text{s} \)

Hint:

Remember: The time period is the reciprocal of the frequency, \( T = \frac{1}{f} \).
