Question

what is the speed of a wave with a wavelength of 3 m and a frequency of.1 hz?
0.03 m/s
0.3 m/s
3.1 m/s
30 m/s

Explanation:

Step1: Recall the wave speed formula

The formula for wave speed \(v\) is \(v = \lambda\times f\), where \(\lambda\) is the wavelength and \(f\) is the frequency.

Step2: Substitute the given values

Given \(\lambda = 3\space m\) and \(f=0.1\space Hz\). Substitute into the formula: \(v=3\times0.1\).

Step3: Calculate the result

\(v = 3\times0.1=0.3\space m/s\)

Answer:

B. \(0.3\space m/s\)
