Question

what is the period of a wave with a wavelength of 8 cm and a frequency of 0.5 hertz? (1 point)
4 seconds
0.125 seconds
2 seconds
0.0625 seconds

Explanation:

Step1: Recall the formula for period and frequency

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

Step2: Substitute the given frequency into the formula

We are given \(f = 0.5\) Hz. Substituting into the formula: \(T=\frac{1}{0.5}\).

Step3: Calculate the period

\(\frac{1}{0.5}=2\) seconds.

Answer:

2 seconds
