Hey dear....
Here is your answer....
SONAR stands for Sound Navigation and Ranging.
Principle and working: It is based on the principle of the reflection of sound wave (i.e., echo).
It can be used to find the depth of the ocean accurately. Powerful pulses of ultrasound are sent out at regular intervals from a transmitter mounted on the ship. When these pulses are intercepted by a distant object or even the sea bottom, they get reflected. The reflected sound or echo is detected by an underwater receiver which is also mounted on the ship. The time interval between transmission and reception of the ultrasonic signal is recorded.
If v is the speed of ultrasound in sea water and t is the elapsed time between the transmission and the reception of the ultrasound signal
unseen object underwater is at a point, then the distance of
h = v X 1/2
Hope it helps you!!!!
