Question

question 15 of 25
what is the period of a wave that has a frequency of 3 hz?
a. 0.3 s
b. 30 s
c. 3 s
d. 300 s

Explanation:

Step1: Recall the formula for period and frequency

The formula relating period \(T\) and frequency \(f\) is \(T=\frac{1}{f}\).

Step2: Substitute the given frequency into the formula

Given \(f = 3\space Hz\), substitute into \(T=\frac{1}{f}\), so \(T=\frac{1}{3}\space s\approx0.33\space s\approx0.3\space s\) (rounded to one - decimal place).

Answer:

A. \(0.3\space s\)
