Question

an ocean wave has a frequency of 2 hz and a speed of 20 m/sec. what is the wavelength of this wave? select one: 0.1 meter 10 meters 20 meters 40 meters check

Explanation:

Step1: Recall wave speed formula

The formula relating wave speed (\(v\)), frequency (\(f\)), and wavelength (\(\lambda\)) is \(v = f\times\lambda\). We need to solve for \(\lambda\), so rearrange the formula to \(\lambda=\frac{v}{f}\).

Step2: Substitute values

Given \(v = 20\space m/s\) and \(f = 2\space Hz\), substitute into the formula: \(\lambda=\frac{20}{2}\).

Step3: Calculate wavelength

\(\frac{20}{2}=10\space meters\).

Answer:

10 meters (corresponding to the option "10 meters")
