time= 1/frequency
so the range in time period 1/20000 s to 1/20 seconds
50 micro seconds to 50 milliseconds

A period tells you how much time it takes for something (sound wave in this example) to complete it's full cycle, and frequency tells you how many cycles you get in 1 sec. So with some thinking you find out that $$T=\frac{1}{f}$$

T - time period
f - frequency
