A wave, traveling with speed v1 through a fluid of density \rho = 1260 kg/m3 , reaches a boundary with a solid material. The absolute value of the amplitude of the transmitted wave is equal to 1/3 of the amplitude of the incident wave. (a) If the wavelength of the transmitted wave increased by 10%, what is the density of the solid material? Give your answer in kg/m3, use 3 significant figures. (b) What percentage of power is transmitted to the solid material? Provide 2 significant figures in your answer.
