The frequencies of the sound waves given off by either a machine or animal bounce off of objects and come back to the animal or machine. As the frequencies travel through the water (or whatever you're using it in) the frequency of the sound waves slow down the further away the object it bounces off of. Therefore, objects that are close to the thing the sound waves came from will come back to it before the sound waves that are further away, making an image.
If someone could reword it to make it less confusing, that would be nice. :)

What is the band name on SpongeBob that sings musical doodle?
It is called "The Sonars"
How do sonars hurt are environment?
They can confuse and hurt whales and dolphins in the ocean.
Similarities and differences between sonograms and sonars?
Sonograms and sonars both use sound waves for imaging purposes, but they differ in their applications. Sonograms are used in medical imaging to visualize internal body structures, while sonars are used in navigation and detecting objects underwater. Both technologies involve emitting sound waves and analyzing the returning signals, but they are designed for distinct purposes.
The reason submarines can detect other underwater objects is largely due to which?
Submarines have sonars.
Are submersibles used to map the ocean floor?
no sonars areNo they are not, a sonar maps the ocean floor.
What are sonars used for?

What is the sailing technology today?
The technology for sailing is electronic sonars, solar panel boats, radars, and computer guidance, as well as sattelite connected devices.
What exactly is garmin sonar for?
A Garmin Sonar is just a specific brand of sonar. Sonars are used primarily for underwater scanning that can detect objects by emitting pulses or "signal waves", and finding the depth of water. Two great sites for finding more about Garmin Sonars are http://garmin.blogs.com/my_weblog/2008/10/an-in-depth-loo.html and http://www.garmin.com/uk/products/marine-products/.
How did the titanic disaster change sea travel?
More efforts were put in to avoid collisions such as detectors like sonars and radars, more lifeboats, and even emergency escape plans
How did boating rules and regulations change after the titanic sunk?
Emergency practice drills HAVE to be in place and boats now have tracking technology such as radars and sonars to better detect problems ahead
