Question

Solve the problems below and show the complete solution.
What is the period (time) of the sound wave produced by a 440 Hertz tuning fork?
T = 1 / f

Answer 1

Let the frequency be $f = 440Hz$. Then the period of the sound wave is given as

$$T = \dfrac{1}{f} = \dfrac{1}{440Hz} \approx 0.0023s = 2.3\space ms$$

Answer. 0.0023 s or 2.3 ms.
