The speed of sound in air is 340 m/s, and the density of air is 1. 2 kg/m3. If the displacement amplitude of a 440-hz sound wave is 10 μm, what is the intensity of the wave?

Respuesta :

The intensity of the wave will be 398.52 W/m². It is power per unit area.

What is a wave?

A wave is a phenomenon that flows across a material medium without leaving any lasting mark.

A disturbance that travels through a medium with a transfer of matter and without a transfer of energy best describes a wave.

The intensity of the wave is found as;

[tex]\rm I = \frac{1}{2} \rho A \omega^2 V \\\\\ I= \frac{1}{2} \times 1.21 \times (10 \times 10^{-6})^2\times (440)\times 340 \\\\ I=398.52 \ W/m^2[/tex]

Hence,the intensity of the wave will be 398.52 W/m².
