Please tell me what is it answer

Answer 1

Sonar is a device which is used to find the depth of sea,or to locate underwater objects like enemy's submarine, sunken ship and shoals of fish.

The application on which it is based is reflection of sound

Answer 2

SONAR is the short form for sound navigation and ranging . It is used to know the distance , speed and direction of an underwater object with the help of ultrasonic sound waves . SONAR has a transmitter and a receiver which are fitted on ships or boats .

The transmitter produces and transmits ultrasonic sound waves . These waves travel through water , strike underwater objects and get reflected by them . The reflected waves are received by the receiver on the ship .

The receiver converts the ultrasonic sound into electrical signals and these signals are properly interpreted . The time difference between transmission and reception is noticed . The time and the velocity of sound in water give the distance from the ship , of the object which reflects the waves .
