Device which uses sound waves for detection and ranging is called

Correct option is B

The correct answer is:(B) Sonar

Explanation:
A Sonar (Sound Navigation and Ranging) system uses sound waves for detection, ranging, and navigation, especially in underwater environments. It is used by submarines, ships, and even in fisheries to detect objects or measure distances underwater. Sonar systems work by emitting sound waves and measuring the time it takes for the waves to reflect back from an object, helping to determine the distance or location of the object.

Information Booster:
• Sonar is widely used for underwater exploration, navigation, and communication.
• There are two types of sonar: active sonar (emits sound waves and listens for reflections) and passive sonar (listens for sounds made by other objects).
• It helps in detecting submarines, underwater hazards, and mapping the ocean floor.
• The speed of sound in water is about 1500 meters per second, and this is used to calculate distances in sonar technology.
• Sonar is crucial in scientific studies like oceanography, where it helps map the seafloor and study marine life.
