Awave travels at a frequency of 387 hz. what is
the period of the wave?

¹/₃₈₇ second

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.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
