In much the same way that a bat uses sonar to locate and hunt its prey, the MIT group determined that ultrasonic frequencies can also be used to detect buried land mines, and even figure out who manufactured them.
Can sonar be used outside of water?
Sonar remains the most effective way to map out the sea floor – but the vast majority of the oceans that form 70 percent of the Earth’s surface remain unmapped, because sonic waves have hitherto only been able to be sent out from underwater.
Is sonar only used underwater?
This technology also relies on sound waves to detect objects. However, sonar is typically used underwater. Medical technicians also may use sound waves to peer inside the human body (which is mostly water).
Does sonar work above water?
Even though SONAR works in the open air, it’s most effective underwater. This has to do with the fact that sound travels further in water.
Where can sonar be used?
Sonar uses sound waves to ‘see’ in the water. NOAA scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and map objects on the seafloor such as shipwrecks, and map the seafloor itself.
