Questions & Step-by-Step Solutions

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.
  • Step 6: By measuring how long it takes for the sound waves to return, the sonar can determine how far away the object is.
