The instrument used to detect submerged objects is called “Sonar”. Sonar stands for Sound Navigation and Ranging. It operates by emitting sound waves into water and detecting the echoes bounced back from underwater objects. Sonar is essential for applications like naval navigation, underwater exploration, fishing, and scientific research in marine environments.

The instrument used to detect submerged objects is called “Sonar” (Option [B]). Sonar stands for Sound Navigation and Ranging. It works by emitting sound waves into water and then detecting the echoes reflected back from underwater objects, such as submarines, ships, or even the seafloor. By measuring the time it takes for the sound waves to return, sonar systems can calculate the distance to these objects and create detailed maps of underwater environments.
Sonar technology is crucial for various applications, including military defense, underwater exploration, navigation, fishing, and marine research. There are different types of sonar systems, such as passive sonar (listening for sounds generated by objects) and active sonar (emitting pulses of sound and analyzing the returning echoes). This technology enables ships to navigate safely through underwater hazards, helps fishermen locate schools of fish, aids in the search and recovery of submerged objects, and supports scientific investigations of oceanography and marine biology.
Options [A] Radar, [C] Quasar, and [D] Pulser are not instruments used for detecting submerged objects, distinguishing them from sonar in underwater detection applications.
