Frequency \(f\) is defined to be the number of events per unit time. For periodic motion, frequency is the number of oscillations per unit time. The relationship between frequency and period is \[f = \dfrac{1}{T},\] The SI unit for frequency is the cycle per second, which is defined to be a hertz (Hz):

Determine the Frequency of Two Oscillations: Medical Ultrasound and the Period of Middle C. 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.
Learning Objectives. Observe the vibrations of a guitar string. Determine the frequency of oscillations. The strings on this guitar vibrate at regular time intervals. (credit: JAR) When you pluck a guitar string, the resulting sound has a steady tone and lasts a long time.
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 \(f = \frac{1}{T}\).
The relationship between frequency and period is. f = f = 1 T 1 T. The SI unit for frequency is the cycle per second, which is defined to be a hertz (Hz): 1 Hz = 1 1 Hz = 1 cycle sec cycle sec or 1 Hz = or 1 Hz = 1 s 1 s. A cycle is one complete oscillation.
