What is SONAR? Write the working?
SONAR is abbreviation of Sound Navigation and Ranging. It is the method used for echoing. Dinars are used to find the depth of the sea or to locate underwater things like shoals of fish, enemy submarines etc. It is used to navigate or detect and communicate with the objects present under water surface such as oceans by using sound propagation. Sonar works by sending short bursts of ultrasonic sound from a ship into the sea and then picking up the echo produced by reflection of ultrasound from underwater objects like the bottom of sea.
