If the wavelength of a wave stays the same, what happens when the wave period increases?

Explanation:

We know that there is a relation between the wavelength and the frequency of wave. It is given by :

Where

v is the speed of a wave

f is the frequency

is the wavelength

Let T is the wave period of a wave. The frequency of a wave is inversely proportional to the time period. Its formula is given by :

When the wave period of the wave increases, its frequency gets decreased. As a result, the speed of wave decreases.

the answer is c. absolute strength measures the greatest force exerted in a single effort, while relative strength measures strength adjusted for body size.
