18. what is the frequency of a spiked wave with a period of 0.45 seconds? a 2.2 hz b 4.4 khz c 45 khz d 2.2 mhz
Answer
Explanation:
Step1: Recall frequency - period relation
The formula is $f=\frac{1}{T}$, where $f$ is frequency and $T$ is period.
Step2: Substitute given period
Given $T = 0.45\ s$, then $f=\frac{1}{0.45}\ Hz\approx2.2\ Hz$.
Answer:
A. 2.2 Hz
