Question

What is the wavelength of a 32800 Hz tone in air? The speed of sound in air is 340 m/s. Answer in units of m.

Answer 1

Given

The frequency is f=32800Hz

Speed of sound in air, v=340 m/s

To find

The wavelength

Explanation

The wavelength is

$\begin{gathered} \lambda=\frac{v}{f} \\ \Rightarrow\lambda=\frac{340}{32800} \\ \Rightarrow\lambda=0.0103m \end{gathered}$

Conclusion

The wavelength is 0.0103 m
