State two applications of an echo.
Echo:
When a sound wave is produced in air, some of it is absorbed after hitting with a reflector while some of the sound wave is reflected back to the listener. This reflected sound is called echo.
Applications of Echo:
1. Since bats cannot see with their eyes, so they use the technique of echolocation to locate their ways. Bats can understand from the reflected sound if there is any object before it. It hunts its prey by using this technique.
2. This technique is also used to find the depth of sea or distance of submarines.
3. It also helps to estimate the distance or hills and mountains.
4. This technique is also very helpful in the medical field as well. Doctors use this phenomenon in cardiography, sonogram and many other medical diagnoses.
