Question

what is the speed of a wave with a frequency of 2 hz and a wavelength of 87 m? 0.023 m/s 43.5 m/s 89 m/s 174 m/s

Explanation:

Step1: Recall the wave - speed formula

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

Step2: Substitute the given values

Given \(f = 2\space Hz\) and \(\lambda=87\space m\). Substitute into the formula: \(v=(2\space Hz)\times(87\space m)\).

Step3: Calculate the value

\(v = 2\times87=174\space m/s\)

Answer:

174 m/s
