Question 1

Calculate the pressure amplitude (in N/m2) of a 500 Hz sound wave in helium if the displacement amplitude is equal to 5.0 × 108 m. (ρ = 0.179 kg/m3, v = 972 m/s.)

3.5 × 102

1.6 × 102

2.7 × 102

4.2 × 102

2.0 × 102


Question 2

Determine the intensity (in W/m2) of a harmonic longitudinal wave with a pressure amplitude of 8.0 × 103 N/m2 propagating down a tube filled with helium. (ρ = 0.179 kg/m3, v = 972 m/s.)

3.7 × 107

1.8 × 107

9.2 × 108

4.6 × 108
