multiple - choice question what formula can we use to find the period? period = frequency / 2π period = 2π /…

Explanation:

Step1: Recall period - frequency relationship

The period ($T$) and frequency ($f$) are inversely related. The general formula for the period of a periodic function in terms of angular frequency $\omega$ is $T=\frac{2\pi}{\omega}$, and when $\omega = 2\pi f$ (where $f$ is the ordinary frequency), we get $T=\frac{2\pi}{2\pi f}=\frac{1}{f}$. In the context of the given options, the correct formula relating period and frequency is period $=\frac{2\pi}{frequency}$.

Answer:

The correct option is: period $=\frac{2\pi}{frequency}$
