Period 0.02 s; frequency?

Explanation:
Period is the time for one complete cycle, and frequency is how many cycles happen each second. The two are linked by f = 1/T. Using T = 0.02 s, f = 1 / 0.02 = 50 Hz. So 0.02 s per cycle corresponds to 50 cycles per second. For reference, other options would require different periods: 0.5 Hz would need a 2 s period, 2 Hz would need 0.5 s, and 200 Hz would need 0.005 s.
