Mary is at a gathering where there is a clarinet player in the background. The clarinets is a pipe open on one end, and has a length L = 35 cm. The clarinet emits sound waves with the oscillation pattern shown in the figure. The speed of sound in air is vs = 343 m/s, and the density of air is ρ = 1.293 kg/m3. (a) (5 pts) What is the frequency of this pattern in Hertz? What is the angular frequency? (b) (5 pts) When Mary is at a distance of r = 3 m, as shown in the figure, the sound level she hears is 67 dB , what is the intensity of the sound at that distance? (c) (5 pts) What is the displacement amplitude of the wave at 5 m , where Mary is standing in part (b)?
