hey here is your answer

SONAR Is the short form for sound Navigation and Ranging . it is used to determine the direction, distance and speed of an underwater object with an help of ultrasonic sound waves. SONAR has a transmitted and a receiver,which are fitted on ships or boats . the transmitted profuced and transmittes ultrasonic sound waves. these waves travel through water,strike underwatercobject 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 it noted . this time and the velocity of sound in water give the distance from the ship ,of the object which reflects the waves . SONAR is used to determines the path of the sea . SONAR is also used to search underwater hills,vallys,submarines,icebergs,sunken ship etc. hope it will help u
