The word SONAR Stands for Sound Navigation And Ranging.
SONAR is an apparatus used to find depth of sea or locate under water things like shoals of fish, sunken ships etc.
Working procedure:
SONAR consist of two parts 1) a transmitter for emitting ultrasonic waves and 2) receiver for detecting ultrasonic waves.
Transmitter sends high frequency sound waves of about 50,000 Hz.This pulse wave travels down to bottom of sea.on striking bottom of sea , it gets reflected BaCk to ship in the form of echo. This echo produces an electrical signal in the receiver part of SONAR device.The SONAR measures the time taken by ultrasound wave to travel from ship to bottom of sea.
Speed = 2 ×distance / TIME (Because of echo).
As we know speed of sound in water is nearly 1500m/ s
We can calculate depth by
Depth = speed x time/ 2
THIS method of finding distance is also called as echo ranging.
Marine geologists use this method to determine depth of sea and locate under water hills and valleys

Echo ranging or Echo location is a technique to determine the size and distance of the body by making special types of sounds with special frequency.
In this technique one has to make special frequency sound that hit the another object and came back to feel like it attracts or something big or small of far or near the person who is practicing echolocation . Bats use echo location to make sound waves that will hit de objects and come back with producing echoes. Same with dolphins even dolphins can produce such sounds that we cant hear.
