Question
An echo is a sound wave that is reflected off of a surface and back to a listener. When sound waves meet a solid substance, the energy may be carried through that substance. Some of it might be absorbed into the substance. In some cases, some might also be reflected off the surface and bounce back. If you hear the same sound again, it’s an echo. Some animals, like bats and dolphins, use echoes to help them navigate. They create sounds and, based on the echoes, they can determine where things are in space. That’s called echolocation.
