What is the formula for calculating the period of a wave?

The formula for calculating the period of a wave is derived from the relationship between frequency and time. The period of a wave, which is the time taken for one complete cycle of the wave to pass a point, is the reciprocal of frequency. Frequency measures how many cycles occur in one second, so the period, being the duration of one cycle, is calculated by taking the inverse of frequency. Therefore, the correct expression is that the period equals one divided by frequency. This fundamental relationship is essential in understanding wave behavior and is widely applicable across various wave phenomena.
