Sonar was not introduced in World War 1.

SONAR is actually an abbreviation for SOund Navigation And Ranging. RADAR is correspondingly an abbreviation for RAdio Detection And Ranging. LIDAR is correspondingly an abbreviation for LIght Detection And Ranging.
The Royal Navy had Asdic for submarine detection. Initially it was quite primitive. I'm thinking Sonar, as such, is more recent than WW2.
Sonar technology, or sound navigation and ranging, significantly aided the Allied war effort during World War II by enabling the detection of submarines and underwater obstacles. By using sonar waves to locate enemy vessels, the Allies improved their anti-submarine warfare capabilities, leading to more effective convoy protection and strategic attacks. This technology also facilitated navigation in treacherous waters, contributing to successful amphibious landings and operations. Overall, sonar played a crucial role in countering the threat posed by German U-boats in the Atlantic.

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.
Sonar stands for Sound Navigation and Ranging. It was first developed during World War I to detect submarines underwater by sending out sound waves and listening for their echoes. The technology has since been adapted for various uses, including underwater mapping and marine research.
sonar is a device for detecting objects underwater by emitting sound waves and analyzing the echoes that bounce back. It is commonly used in navigation, fishing, and underwater mapping.
Scientists determined the location and size of the underwater mountain chain through methods such as bathymetric mapping using sonar, satellite data, and submersible vehicles. By studying these tools and data, scientists were able to create detailed maps of the seafloor, revealing the location and size of underwater mountain chains.
It uses echo location for all underwater submarines and when the signal comes back you will be able to see whats in front of you.
Sonar was not introduced in World War 1.
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.
they use SONAR. :)
Sonar was important for detecting underwater objects, such as submarines or shoals, by transmitting sound waves and listening for the echoes. This technology was particularly crucial during wartime for naval operations and underwater exploration. Additionally, sonar helped in mapping the ocean floor and studying marine life.
