A wave is propagating in an aluminum block surrounded by water (you can consider Material 1 as Aluminum and Material 2 as Water). The pressure amplitude of the incident wave is 10 N/m. (Aluminum) Density=2,700kg/m Speed = 6,200m/sec P=10 W (Water) Density=1,000kg/m Speed = 1,500m/sec 3 a) Compute Pr, Pt of the reflected and transmitted waves and show a drawing of the waves similar to the one in the notes. b) Show that there is conservation of energy.
