What technology uses sound waves, often underwater, to detect objects and measure depth?

Explanation

Sonar, short for sound navigation and ranging, works by emitting sound waves underwater and measuring how long it takes for the echoes to bounce back after hitting an object, such as the seabed or a submarine. This allows ships and submarines to measure water depth, detect obstacles, and locate marine life or other vessels. Sonar is essential for underwater navigation, since light and radio waves do not travel well through water over long distances. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
