Question

What is the period of vibration for a wave with a frequency of 50 hertz? 50 seconds 500 seconds 2 seconds 0.02 seconds

Answer 1

i think the answer is 0.02

Answer 2

Answer:

Time period, T = 0.02 seconds

Explanation:

It is given that,

The frequency of a wave, f = 50 hertz

We need to find the period of vibration of the wave. The frequency of a wave is defined as the reciprocal of its time period.

i.e.

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

$T=\dfrac{1}{50\ Hz}$

T = 0.02 seconds

So, the period of vibration of the wave is 0.02 seconds. Hence, the correct option is (d).
