We can use the formulas presented in this module to determine both the frequency based on known oscillations and the oscillation based on a known frequency. Let’s try one example of each. A medical imaging device produces ultrasound by oscillating with a period of 0.400 µs.
By rearranging the above formula so that its subject is frequency, you can derive the following formula for the time period of oscillations (T): T = 1 = 2π. f ω. Using the measurements described in the section above, you can use the following formulas with simple harmonic oscillators: = x Acos ωt. v = − A ωsin ωt. a = − A ω 2 cos ωt.
Periodic motion is a repeating oscillation. The time for one oscillation is the period T and the number of oscillations per unit time is the frequency f. These quantities are related by \(f = \frac{1}{T}\).

1. One of the most important examples of periodic motion is simple harmonic motion (SHM), in which some physical quantity varies sinusoidally. Suppose a function of time has the form of a sine wave function, y(t) = Asin(2πt / T ) (23.1.1) where A > 0 is the amplitude (maximum value).

If you wish to see the sort of gyrations necessary to get a formula that can be solved with a calculator, see for example F.M.S. Lima and P. Arun, “An accurate formula for the period of a simple pendulum oscillating beyond the small angle regime”,
