Q. SOFAR is a phenomenon which plays an important role in submarine warfare & also known as deep sound channel. Which of the following is correct full form of SOFAR?
Answer: Sound Fixing and Ranging channel
Notes: The correct full form of SOFAR is "Sound Fixing and Ranging." This phenomenon occurs in the ocean where sound waves travel along a channel at a specific depth, allowing submarines to communicate and navigate effectively. The SOFAR channel is crucial for long-distance underwater communication, as sound can travel thousands of kilometers with minimal loss. It is formed due to variations in water temperature and pressure, creating a zone where sound waves are trapped.
