Question

Describe how a fisherman can use sonar to find a shoal of fish.

Answer 1

Answer:

Sonars send sound waves or signals into the water that rebound when they strike an object. The fish reflects some of the signal back to the boat, the remainder of the signal continues to the seafloor then it bounces back to the boat. ... Fish finding sonar units send and receive signals many times per second.
