The relationship between frequency (f) and the period (T), which represents the time for one complete cycle, follows a direct formula. Frequency is defined as the number of cycles per unit of time, while the period is the duration of one cycle. The mathematical relationship is expressed as:

f = 1 / T

This means that if you know the period of a cycle (T), you can find the frequency (f) by calculating the reciprocal of T. Conversely, if you know the frequency, you can find the period by calculating the reciprocal of the frequency. Because of this foundational relationship, the formula 1 ÷ T accurately represents how frequency is derived from the time for one complete cycle, confirming that frequency increases as the time for one cycle decreases.

Other relationships, such as T ÷ 1 or T × f, do not appropriately reflect the conventional definitions of frequency and period. Thus, option A succinctly and accurately conveys the correct relationship between these two fundamental concepts in physics and wave mechanics.
