Question

1. period and frequency are inversely related. what happens to the frequency if the period increases?

the frequency stays the same.
the value of the frequency is squared.
the frequency is doubled.
the frequency decreases.

Explanation:

Period ($T$) and frequency ($f$) have an inverse relationship defined by $f=\frac{1}{T}$. When the period $T$ increases, the value of $\frac{1}{T}$ decreases, so the corresponding frequency $f$ must decrease.

Answer:

The frequency decreases.
