elena-s [515]

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.
