in the configuration below, the average power density produced by the transducer radiating into the dat is 10 mW/cm^2. If the area pf the trasmdicer is 10 cm^2 and its frequency is 3MHz, determine how much average power will be received back at the transducer from the reflection at the fat/kidney interface. Neglect beam spreading
