Questions & Step-by-Step Solutions

What is the principle behind sonar technology?
Correct Answer: Sonar technology is based on the reflection of sound waves to detect objects underwater.
  • 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.
  • Step 4: When the sound waves hit an object, they bounce back.
  • Step 5: The sonar system listens for the returning sound waves.
  • Step 6: By measuring how long it takes for the sound waves to return, the system can determine how far away the object is.
