For each frequency entered a conversion scale will display for a range of frequency versus period values. T 2 pi o The inverse of the period is called frequency. It still tells you how often something happens but the thing is a complete oscillation of the moving object or wave and the time period is always the second.
As such the formula for calculating frequency when given the time taken to complete a wave cycle is written as.
T period the time required for one cycle. The corresponding expression is. A wave has a frequency of 2000 Hz determine its period. Therefore the wave period is 00005 seconds.
