Question:

The average power density produced by the transducer radiating into the dat is 10 mW/cm². If the area pf the transducer is 10 cm² 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.
