Answer:

They are inversely related.

Step-by-step explanation:

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

$v=\\u * \lambda$

Here,

$\\u$ = frequency of a wave

$\lambda$ = wavelength of a wave

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

$v=(\lambda)/(T)$ , 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.
