Product description
A plane harmonic sound wave propagates through air. Air density 1.3 kg/m^3, atmospheric pressure 10^5 Pa. The energy transferred during the time t = 1 min through the area S = 0.6 m^2, perpendicular to the direction of wave propagation, is equal to W = 0.36 mJ. The phase difference of oscillations between two points is n/5 rad, the distance between these points is 0.25 m. Write the wave equation. Determine the amplitude of the acoustic pressure and the intensity level of the wave.
