The period of the sound wave at the given frequency is determined as 0.00235 second.
<h3>
Period of the sound wave</h3>
The period of the sound wave at the given frequency is calculated as follows;
Period is reciprocal of frequency.
T = 1/f
T = 1/425
T = 0.00235 second
Thus, the period of the sound wave at the given frequency is determined as 0.00235 second.
