The impedance of a material is Z=rhoc, the density times the speed of sound. Consider the following information: Zlung=0.18×106kg s/m2. Zfat=1.34×106kg s/m2. What fraction of the incident intensity of a sound pulse will be reflected when sound travels from fat into lung? Express your answer in percent.
