Answer 1

Explanation:

Animals such as bats and dolphins send out ultrasound waves and use their echoes to identify the locations of objects they cannot see. This is called echolocation. Sonar stands for sound navigation and ranging. It is used to locate underwater objects such as submarines.

Answer 2

Answer:

Ultrasound waves are produced by a transducer, which can both emit ultrasound waves, as well as detect the ultrasound echoes reflected back. In most cases, the active elements in ultrasound transducers are made of special ceramic crystal materials called piezoelectrics.
