What is Echolocation?
Echolocation is a method of navigation for animals such as bottlenose dolphins and bats. It is considered as one of the most advanced sonar systems of the world. The term "sonar" stands for "sound navigation and ranging". It is a technique used to identify and recognize objects located, typically, underwater. Sonar systems radiate sound waves, which reflect off an object or signal, and returns to the sonar system, where the echo of the soundwave is interpreted. Sonar systems are used to map out sea floors, navigating torpedoes, submarine navigation, fishing, ultrasound, and are also used by animals. Bats and bottlenose dolphins are one of the many animals, which use sonar waves to replace their poor eyesight. How can echolocation exactly be used to replace eyesight?
