Answer 2

The full form of SONAR is SOund Navigation and Ranging. The method of SONAR is also called echo ranging. It is a device that utilizes ultrasonic waves to estimate and measure the distance, direction and speed of objects underwater.

Principal of SONAR:-

It uses echoes in to determine the sea-depth and locating the presence of objects underwater.

Working of SONAR:

• The transmitter in SONAR produces and transmits powerful ultrasonic waves.
• The ultrasonic waves travel through the water and after striking the target the beam is reflected from the seabed and is received by an under-water detector (mounted on the ship).
• The detector then converts the waves into electrical signals which are properly interpreted.
• The time interval between transmission and reception of the signal is also noted.
