Time period (T) = Time taken for one oscillation
T = (2 min × 60 s/min) / 1200 = 0.1 seconds
_______________
Frequency (f) = Total number of oscillations in 1 second
f = 1/T = 1/(0.1 s) = 10 Hz
T = (2 min × 60 s/min) / 1200 = 0.1 seconds
_______________
Frequency (f) = Total number of oscillations in 1 second
f = 1/T = 1/(0.1 s) = 10 Hz

Number of oscillations = 1200
Time taken = 2 min = 120 sec
Time period = 120/1200 = 0.1 sec
Frequency = 1/T = 1/0.1 = 10 Hz
Hope it helps
