Side-scan sonar

Side-scan sonar is like a special camera that can take pictures of things hidden under the water, like a treasure or a sunken ship. It works by sending out sound waves that bounce off objects in the water and come back to the machine.

The machine then uses the bounced sound waves to make a picture of everything under the water, showing different shapes and sizes. This picture can help people see what's under the water without having to dive down and look themselves. It's like a big flashlight that goes through the water, but instead of making light, it makes sound waves!

Scientists and fishermen use side-scan sonar to help them find fish, underwater mountains, sunken ships, and other things they might be interested in. It's a really cool tool that helps us explore and learn about the world beneath the surface of the water!
