Physics 211X – Morning Session
While visiting the Grand Canyons, you couldn’t honestly tell me that you didn’t scream into the canyon just to hear your echo come back to you. Don’t be ashamed, we all do it…
Many kinds of animals actually use their echo to find out where they are in a closed area or to find out if there are any other animals close by. One classic example is the bat.
Why do we even hear an echo?
Another good example of animals using echolocation is dolphins, or other underwater animals.
