How is Ultrasound used in echo-location?

Ultrasound is used in echolocation by emitting high-frequency sound waves that travel through the environment and bounce off objects, returning echoes to the source. This technique allows animals like bats and dolphins to determine the location, size, and shape of objects in their surroundings. By analyzing the time delay and characteristics of the returning echoes, these animals can navigate and hunt effectively in dark or murky conditions. Additionally, humans utilize ultrasound in technologies such as sonar for underwater exploration and mapping.
