sonar was discorvered in 1840 the early sientist Sarah Nolsoc. but first used by Samantha Layor
the Challenger
sonar,is used to map mid-ocean ridges:]
One technology oceanographers use to explore the ocean floor is multibeam sonar. This advanced sonar system emits multiple sonar beams in a fan shape to create a detailed 3D map of the seafloor topography. Multibeam sonar helps scientists to accurately study the features and structures of the ocean floor.
Sonar is a method of sound based ranging. Therefore as an object it is not subject to an antonym. There is the principal of radar which can also range, but it uses radio waves instead.
Sonar (Sound Navigation and Ranging) is the system that uses the reflection of underwater sound waves to detect objects. This technology is commonly used in naval navigation, fishing, and underwater mapping.
Lewis Nixon did not invent sonar. Sonar was actually invented by Reginald Fessenden in 1913. Sonar stands for sound navigation and ranging, which is a technique that uses sound propagation to navigate, communicate with, or detect objects underwater.
The Sonar device was invented in 1906 by Lewis Nixon. -T
in 1912
it didnt
It was Lewis Nixon who invented the very first sonar-type listening device in 1906.
Sonar was gradually developed and improved over many years, but the first operational form of sonar as we now know it goes back to about 1918.
The 1925 Meteor Sonar was invented by Albert Beaumont Wood, a British engineer and inventor. His work with sonar technology significantly contributed to advancements in underwater acoustics during that time.
I believe that Lewis Nixon was 45 when he invented sonar. He was born in 1861. Kelly Nixon Mayr
A Canadian inventor named Reginald Fessenden invented SONAR in the early 20th century.
The scientist who is credited with inventing sonar is Paul Langevin, a French physicist. In 1915, Langevin developed the first practical application of sonar as a way to detect submarines during World War I. His work laid the foundation for the use of sonar technology in various fields, including marine navigation and underwater exploration.
The LAtin word for sound and noise is sonitus. There was not a word for sonars. The Romans did not have sonar. It was invented in the 1930s. Additionally, SONAR isn't a word, it's an acronym: SOund Navigation And Ranging.
i would guess ww2 to detect enemy subs
