What is the principle behind the working of a sonar?

Step 1: Sonar stands for Sound Navigation and Ranging.
Step 2: Sonar sends out sound waves into the water.
Step 3: These sound waves travel through the water until they hit an object, like a fish or the ocean floor.
Step 4: When the sound waves hit an object, they bounce back towards the sonar device.
Step 5: The sonar device listens for the returning sound waves.
