A period is the time taken for one complete wave to pass a point.

A period is the time taken for a single oscillation to occur.

A period is a scalar quantity because it has magnitude but no direction.

Period may refer to the time taken for an oscillating object such as a pendulum or mass on a spring to make one full oscillation.

Period may refer to the time taken for one wave to pass a point.

NB: You do not need to remember this equation but you should be able to find the period of a wave using the frequency.

Period = 1/(Frequency)

\(T = \frac{1}{f}\)

Where:

T = time period (the time it takes for one wave to pass a point).

A wave has a frequency of 0.2Hz. Calculate how long it takes for one wave to pass a point.	The E-string on a bass guitar is plucked to produce a sound with a frequency of 41.25Hz. Calculate the time it takes for the E-string to make one full oscillation.
1. State the known quantities f = 0.2Hz	1. State the known quantities f = 41.25Hz
2. Substitute the numbers into the equation and solve. \(T = \frac{1}{0.2}\) \(T = 5s\)	2. Substitute the numbers into the equation and solve. \(T = \frac{1}{40}\) \(T = 0.024s\)
