A sound wave in air at 20 Celsius has a frequency of 151 Hz and a displacement amplitude of 5.40×10-3 mm.
Part A For this sound wave calculate the pressure amplitude (in Pa).
Use 1.42×105 Pa for the adiabatic bulk modulus.
Pmax= 2.11 Pa
Part B Find the intensity of the wave
Use 1.20 kg/m^3 for the density of air.
I=?
