Question

For sound waves, which travel at 343 m/s in air at room temperature, what frequency corresponds to a wavelength of 2.00 m ?

Answer 1

`\begin{gathered} v=\lambda f \\ \lambda=wavelength=2.00m \\ v=343\text{ m/s} \\ 343\text{ m/s=(2.00m)f} \\ \text{Solving f} \\ f=\frac{343\text{ m/s}}{2.00m} \\ f=171.5\text{ Hz} \\ \text{The frequency is }171.5\text{ Hz} \end{gathered}`
