Question

How is the speed of a mechanical wave related to its period?

They are directly related.
They are inversely related.
They are not related.
They are related by a factor of g.

Answer 1

Answer:

They are inversely related.

Explanation:

The speed of any wave is given in terms of its wavelength and frequency as follows :

$v=\nu \times \lambda$

Here,

$\nu$ = frequency of a wave

$\lambda$ = wavelength of a wave

Also, the frequency of a wave is reciprocal of its frequency. So, the formula becomes :

$v=\dfrac{\lambda}{T}$, T is the time period of a wave

It is clear from above that the speed of a mechanical wave is inversely proportional to its time period. Hence, b is correct option.
