Sonar uses sound. It helps you check all around.
It can help you find a fish. Or a submarine if you wish.

Radar uses radio. Got your boom box in tow.
You can predict the weather. You can land your plane as light as a feather.

Lidar uses light. Measuring wind on a stormy night.
The position of an earthquake. A map of Mars that takes the cake.
