Frequency is a number of cycles per second.
f = frequency, T = time period, f = 1/T
In case of period - time per cycle. So, t/cycles (just reverse)
20/10 = 2 micro second.
f = frequency, T = time period, f = 1/T
In case of period - time per cycle. So, t/cycles (just reverse)
20/10 = 2 micro second.

It's not the frequency,
The Period is the number of cycles per sec. Period and frequency are different.
The Period is the number of cycles per sec. Period and frequency are different.

Frequency is no. of cycles per second.
So, t=2 micro sec.
So, t=2 micro sec.

Freq= no.of cycles/ time period.
Here,
F= 10/20 = 0.5.
Time = 1/f = 1/0.5 = 2.
Here,
F= 10/20 = 0.5.
Time = 1/f = 1/0.5 = 2.

Period = Time/Cycle
= 20/ 10
= 2
= 20/ 10
= 2
