Answer:

I = 9.82 10⁻⁷ W / m²

Explanation:

The intensity of the sound wave is the energy of the wave between the order per unit area of ​​the same

      I = P / A = E / T A

the energy is calculated by integrating the mechanical energy in a period, where the mass is changed by the density and ‘s’ is the amplitude of the sound wave

     I = ½ ρ v (w s)²

   

     I = ½ 1.35 328 (2π 530 2.00 10⁻⁸)²

     I = 221.4 (4.435 10⁻⁹)

     I = 9.82 10⁻⁷ W / m²
