Question

1. a wave has a wavelength of 0.5 meters and a frequency of 120 hz. what is the waves speed?

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 \(\lambda = 0.5\space m\) and \(f=120\space Hz\). Substitute into the formula: \(v=(0.5\space m)\times(120\space Hz)\)

Step3: Calculate the wave speed

\(v = 0.5\times120=60\space m/s\)

Answer:

The wave's speed is \(60\space m/s\)
