Question

velocity = 320 m/s
wavelength = 80 m
frequency = ___ hz

Explanation:

Step1: Determine the formula

From the triangle, we can get the formula \(v = f\times\lambda\), where \(v\) is velocity, \(f\) is frequency, and \(\lambda\) is wavelength. We need to find \(f\), so we can rewrite the formula as \(f=\frac{v}{\lambda}\).

Step2: Substitute the values

Given \(v = 320\space m/s\) and \(\lambda=80\space m\). Substitute these values into the formula \(f=\frac{v}{\lambda}\), we get \(f=\frac{320}{80}\).

Step3: Calculate the result

\(f = 4\)

Answer:

\(4\)
