Bats Use Sonar

The video tutorial explores the development and functionality of radar and sonar technologies. Radar, developed in the early 20th century, uses radio waves to detect objects, measure speed, and create maps. It is widely used in weather forecasting, aviation, and law enforcement. Sonar, which uses sound waves, is used in navigation and medical imaging, with natural examples found in bats and dolphins. Both technologies rely on wave reflection to determine object location and movement.
