Question

a sound wave has a frequency of 220 hz and travels through air at 330 m/s. what is its wavelength? answer: type your answer... m

Explanation:

Step1: Recall the wave formula

The formula relating wave speed (\(v\)), frequency (\(f\)) and wavelength (\(\lambda\)) is \(v = f\lambda\), so we can rearrange it to find wavelength: \(\lambda=\frac{v}{f}\)

Step2: Substitute the given values

We know \(v = 330\space m/s\) and \(f = 220\space Hz\). Substituting these into the formula: \(\lambda=\frac{330}{220}\)

Step3: Simplify the fraction

\(\frac{330}{220}=\frac{3}{2} = 1.5\)

Answer:

1.5
