What is the frequency corresponding to a period of 0.04 seconds?

Explanation:
Frequency is how many cycles happen each second, so it’s the reciprocal of the period: f = 1/T. With a period of 0.04 seconds, the frequency is 1 / 0.04 = 25 Hz. That means 25 cycles occur every second. For a sense of scale, a longer period like 0.25 s would give 4 Hz, and a shorter period like 0.025 s would give 40 Hz. The given period directly corresponds to 25 Hz.
