To measure how deep the ocean is, scientists send a solar signal to the ocean floor. It bounces off the floor and travels back up to the surface. This is called an echo. Have you ever heard your voice echo off a distant hill? The sound bounces off the surface and back to your ears.
Scientists measure the time it takes for the echo to reach the surface. Then they do some calculations. This tells them how far down the ocean floor is. This is important information for ships and submarines traveling in the ocean.

Sound NAvigation and Ranging—SONAR—is used to find and identify objects in water. It is also used determine water depth (bathymetry). Sonar is applied to water-based activities because sound waves attenuate (taper off) less in water as they travel than do radar and light waves. Sonar was first used during World War I to detect submarines. By the 1920s, the U.S. Coast and Geodetic Survey—the precursor to NOAA’s National Ocean Service—was using it to map deep-water areas. The technology steadily improved, and by World War II, was used once again for military purposes.

hello its me
What is the origin of sonar?
The oragin of the sonar in whales in dolpins. They were the first to use ecolocation to ee under water.
Why light cannot be used in SONAR?
SONAR is an acronym for Sound Navigation And Ranging. LIDAR would use light.
Why do scientists use sonar?
to calculate the depth of the ocean floor
Is sonar harmful?
Sonar has been linked to injury and to the stranding of whales and some other marine mammals. It is difficult to actually prove a "causal connection" between sonar and the injuries and strandings, but oceanographers and marine biologists are working on this issue. Laws have been passed recently in the U.S. and the military has been given a Presidential override on their use of sonar because it is too important to national security to restrict its use.
How did sonar change society?
Your fathers mustache is now responsive to the waves SONAR detects.

How do use sonar in a sentence?
We can use sonar to map the lake's floor.
How do dolphins hear underwater?
they use SONAR. :)
What is the benefit of sonar?
It helps find things underwater. Whales and dolphins use sonar to locate food and obstacles. Sonar is a useful tool in warfare: it can be used to locate and avoid obstacles. Sonar technology has allowed for safer sea travel. The assurance of safe travel attracts more travellers, thus bringing more income into the sea travel business. Sea travel is and was a driving force in the process of globalisation (this is basically the interconnectedness of the world), so, in summary, an impact/benefit of sonar on the world is that it was one of the driving forces of globalisation.
What do Scientsts use sonar for?
Scientsts use sonar to map the depth of water in sea and river etc..,they also use sonar to locate and identify object underwater
How does CAD benefit society?
We use cad to make our work easier
How is sonar similar to vocal?
Exactly the same. Sonar is Sound. We use the word sonar to indicate what use that the sound is put to- not to differentiate it from sound its self.
How do you use sonar in a sentence?

Do dogs use sonar?
dogs do not use sonar. but if you mean ecolocation then no as well. but they do have incrediablely sensitive nose.
Could fisherman use sonar?
Many species of sharks do not use sonar, as they have very effective senses, but some species are thought to. The hammerhead shark, in particular, is thought to use sonar waves detection.
