Answer: The pulse travels downward through the water, reflects off the ocean bottom, and then returns to the surface where it is detected by the transducer.

Answer:

In a basic, single-beam sonar system, a combined transmitter and receiver, called a transducer, mounted on the bottom of a ship generates a single sound pulse. The pulse travels downward through the water, reflects off the ocean bottom, and then returns to the surface where it is detected by the transducer.
