Answer 1

Answer:

Sonar is an acoustic wave (whose uses are roughly analogous to radar) and whose name is an acronym for "sound navigation and ranging." Sonar consists of pulses of sound waves are transmitted into water, usually at ultrasonic frequencies in the range of 20-100 kHz. They travel out and are reflected by a solid object.

Answer 2

Sonar is the measurement of that frequency of sound which can be hear by human ears that is from 20 Hz - 20,000 Hz

the sounds with frequency less than 20 Hz are called infrasonic sounds

and the sounds with frequency higher than 20,000 Hz are called ultrasonic sounds.
