What is the relationship between frequency and period?
Frequency, f, is the number of oscillation cycles that occur every second and is measured in cycles per second or hertz (Hz). The period of a wave, T, is the length of time it takes for a wave to complete one full cycle of vibration. These two terms have an inverse relationship: f = 1/T and T = 1/f.

What is frequency?
Frequency, or f, is the number of times an event occurs in a specific length of time. Any repeating event can be measured for frequency. Examples would be the number of visits a website gets in a day or how regularly a customer purchases the same product in one year. Hertz, or Hz, is the unit of measurement applied to frequency. Hertz measures the number of times an event repeats in one minute. Period, or T, is the amount of time it takes for one cycle of a repeating event to happen.
