Question

Time period of an object is 0.004 second calculated it's frequency

Answer 1

Answer:

We know,

$t = \frac{1}{f} \\ = \frac{1}{0.004 } \\ = 250$

Therefore, 0.004s= 250Hz

Answer 2

Answer:

$since \: time \: period \: = \frac{1}{frequency} \\ hence \: \\ f = \frac{1}{time \: period \: } \\ \: f \: = \frac{1}{0.004} \\ \: f \: = 250 \: hz$
