Answer:

0.132 meters is the wavelength of sounds to which people are most sensitive.

Explanation:

Frequency of the sound human ears are most sensitive to = $\nu = 2500Hz=2500 s^{-1}$

Speed of the sound wave = S = 330 m/s

Wavelength of the sound human ears are most sensitive to = $\lambda = ?$

$\nu=\frac{S}{\lambda }$

$2500 s^{-1}=\frac{330 m/s}{\lambda }$

$\lambda =\frac{330 m/s}{2500 s^{-1}}=0.132 m$

0.132 meters is the wavelength of sounds to which people are most sensitive.
