Question

The frequency of a wave is 0.25 Hz. Find the time period of the vibration. ​

Answer 1

Answer:

4 seconds

Explanation:

,

because

frequency is no. of vibrations in 1 second= 0.25hz

Answer 2

Answer:

The time period of the vibration at given frequency is 4seconds.

Explanation:

Given the frequency of a wave, $f= 0.25 Hz$

The time taken by a wave to complete one vibration is called the time period $T$ of a wave.

The frequency $f$ of wave is defined as the number of vibrations per second. Frequency is measured in Hertz(Hz).

Therefore, the relation between the time period and frequency of a wave is given by

 $T=\dfrac{1}{f}$

Substituting the given value of frequency, the time period of the vibration is

$T=\dfrac{1}{0.25}=4sec$

Hence, the time period of the vibration at given frequency is 4seconds.
