Period, T = (time taken, t)/(number of cycles, n); Also, T = 1/(frequency, F),
Therefore, T = (1/100) = 0.01s,
So, n = (t/T) = (12/0.01) = 1200 cycles.

F=cycle^seond.
100 = cycle/12.

F = 1/t
So,100 = 1/12,
= 100 * 12,
= 1200.

Sine wave completes 100 cycles in 1 sec and for 12 sec its 100*12 = 1200 cycles.

Frequency = Number of cycles / Unit time
No of cycles = Frequency * Unit time
Frequency =100Hz Time=12s
No of cycles = 100*12= 1200 cycles

As 50hz is 50cycle per sec than
100hz is 100cycle per sec
100hz in 12 sec is
100*12=1200 cycle
