The

**period**is the duration of time of one**cycle**in a repeating event, so the**period**is the**reciprocal**of the**frequency**. For example, if a newborn baby's heart beats at a**frequency**of 120 times a minute, its**period**—the time interval between beats—is half a second (that is, 60 seconds divided by 120 beats).In this regard, what is the relationship between the frequency and the period of a wave?

Frequency, f, is how many cycles of an oscillation occur

**per second**and is measured in cycles**per second**or hertz (Hz). The period of a wave, T, is the amount of time it takes a wave to vibrate one full cycle. These two terms are inversely**proportional**to**each other**: f = 1/T and T = 1/f.Are frequency and wavelength directly or inversely related?

Assuming a sinusoidal wave moving at a fixed wave speed,

**wavelength**is**inversely proportional**to**frequency**of the wave: waves with higher**frequencies**have shorter**wavelengths**, and lower**frequencies**have longer**wavelengths**.
