A person is able to hear sound waves within the frequency range of...

Given, speed of sound, $v = 360 \text{ m s}^{-1}$

Minimum frequency, f_\min = 20 \text{ Hz}

Maximum frequency, f_\max = 20 \text{ kHz} = 20000 \text{ Hz}

The relation between speed, frequency, and wavelength is given by $v = f \lambda \Rightarrow \lambda = \dfrac{v}{f}$

For minimum wavelength, frequency must be maximum:

\lambda_\min = \dfrac{v}{f_\max} = \dfrac{360}{20000} = 18 \times 10^{-3} \text{ m} = 18 \text{ mm}

For maximum wavelength, frequency must be minimum:

\lambda_\max = \dfrac{v}{f_\min} = \dfrac{360}{20} = 18 \text{ m}

Thus, the minimum and maximum wavelengths are $18 \text{ mm}$ and $18 \text{ m}$ respectively.
