Question

a wave with a period of 0.008 seconds has a frequency of a) 125 hz. b) 12.5 hz. c) 800 hz. d) 80 hz

Explanation:

Step1: Recall the formula for frequency and period

The relationship between frequency ($f$) and period ($T$) is $f = \frac{1}{T}$, where the period $T$ is in seconds and frequency $f$ is in hertz (Hz).

Step2: Substitute the given period into the formula

We are given that $T = 0.008$ seconds. Substituting this into the formula $f=\frac{1}{T}$, we get $f=\frac{1}{0.008}$.

Step3: Calculate the value

Calculating $\frac{1}{0.008}$, we can rewrite $0.008$ as $\frac{8}{1000}=\frac{1}{125}$. So, $\frac{1}{0.008}=\frac{1}{\frac{1}{125}} = 125$ Hz.

Answer:

A) 125 Hz
