Time period =total time taken /no of oscillation =3/21=1/9=0.9sec
Frequency =no of oscillation /total time taken =21/3=9hertz
Frequency =no of oscillation /total time taken =21/3=9hertz

frequency is oscillations per second.
so, 21/3 = 9 Hz
f = 1/t
so, t = 1/f
which is approximately = 0.11 s
so, 21/3 = 9 Hz
f = 1/t
so, t = 1/f
which is approximately = 0.11 s
