Question

the frequency of a wave is 4hertz find its time period

Answer 1

$\boxed{hello}$

Frequency of a wave = 4 Hz

Time period = ?

We know,
$\boxed{frequency \: (f) \: = \frac{1}{time \: period \: (t)} }$

Using, this formula

4 = 1/t

=> t = 1/4

=> t = 0.25 seconds

Answer 2

Frequency of a wave = 4 Hz

Time period = ?

We know,  

\boxed{frequency \: (f) \:  =  \frac{1}{time \: period \: (t)} }

Using, this formula

4 = 1/t

=> t = 1/4

=> t = 0.25 seconds
