Question

A wave travels at a frequency of 387 Hz. What is
the period of the wave?
​

Answer 1

¹/₃₈₇ second

Step-by-step explanation:

The period of a wave is the reciprocal of its frequency.

So here, the period would be ¹/₃₈₇ second, which means a point in the wave goes to its original location every ¹/₃₈₇ second.
