Frequency is defined as the number of cycles per ______.

Explanation:
Frequency is the rate at which something repeats, measured as how many cycles occur in a given amount of time. The natural time unit is the second, so frequency is cycles per second. That’s why the standard unit is the hertz (Hz), defined as one cycle per second. The other options don’t fit the phrase: a meter is a unit of length, a pulse isn’t a time unit, and while Hertz is the unit for frequency, you wouldn’t fill the blank with it because the phrase requires a time interval.
