What is the period of the crystal's motion?

Question

A quartz crystal vibrates with a frequency of 26,621 Hz. What is the period of the crystal's motion?

Answer 1

Calculate the inverse of 26.621 kHz to find the period in ms:

1/26.621 ≈ 0.037564 ms = 37.564 μs (the answer)

Answer 2

Frequency = 1/Time period

So Time period = 1/ Frequency = 1/26621 Sec =0.00003756 Sec = 3.76 *10^-5 Sec
