Find the frequency of a tuning fork that takes $2.50\times 10^{-3}\text{ s}$ to complete one oscillation.

This is College Physics Answers with Shaun Dychko. Frequency is the reciprocal of period, so we're told that the tuning fork takes two and a half milliseconds or two and a half times ten to the minus three seconds to do one oscillation. So one divided by that gives 400 Hertz as the frequency.
