Seeing With Sound

Some animals, like bats and dolphins, use sound instead of light to work out the location of objects. This is called echolocation. It allows the animal to move around in the dark so they can find food and avoid bumping into things. Incredibly, blind people can also learn to use echolocation.

You are able to read these words because you can see them. Maybe you are reading them off the screen of a mobile device. A screen emits (gives out) light. It is a light source,or luminous object.The light from the screen travels in a straight line and enters your eyes, so you can see the words. Light-sensitive cells in the back of your eye detect the light and send messages along a nerve to your brain.
