Question

Find the frequency in Hertz (Hz) for the following situations:

a) a basketball team scores 40 points in 300s

b) a tuning fork vibrates 2000 times in 2s

c) a boat bobs up and down 20 times in 5 minutes

Answer 1

a) f =40/300=0.133 s^-1.
b) f = 2000/2 = 1000 s^-1.
c) f = 20/5•60 = 20/300 =0.067 s^-1

Answer 2

I thought frequency is 1/T . T as in Period. ..

Answer 3

Frequency – f - is the number of occurrences of a repeating event per unit time.
The period – T -is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency.
T = 1/f.
[ T ] = seconds = s
[ f ] = s^-1 = Hz
