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.
[tex]T=\dfrac{1}{f}[/tex]
[tex]T=\dfrac{1}{50\ Hz}[/tex]
T = 0.02 seconds
So, the period of vibration of the wave is 0.02 seconds. Hence, the correct option is (d).
