Question

what is the frequency of a wave whose time period is 0.015 seconds?

Answer 1

We know that,

F=1/time period

therefore, F== 1000/15
= 66.66 Hz ans.
hope it helps

Answer 2

Given:

• Time period of wave = 0.015 sec

To find:

• Frequency of the wave ?

Calculation:

• Frequency is defined as the total number of complete oscillations made by the medium particles in 1 second.

• In other words, frequency is often said to be the reciprocal of time period.

$frequency = \dfrac{1}{Time \: period}$

$\implies f = \dfrac{1}{T}$

$\implies f = \dfrac{1}{0.015}$

$\implies f = \dfrac{1000}{15}$

$\implies f = 66.67 \: hz$

So , frequency of the wave is 66.67 Hz.
