The energy partition between reflected and refracted plane ultrasonic waves at water-solid and solid-water boundaries is considered. Some general features are discussed and applications of the results to velocity measurements are pointed out. Results of calculations for a Plexiglas-water boundary show that the curves one obtains are quite dissimilar if one either considers or neglects the shear wave in the Plexiglas.
