In 1915, Paul Langévin invented the first sonar type device for detecting submarines called an "echo location to detect submarines" using the piezoelectric properties of the quartz. He was too late to help very much with the war effort, however, Langévin's work heavily influenced future sonar designs.
The first Sonar devices were passive listening devices - no signals were sent out. By 1918, both Britain and the U.S had built active systems, in active Sonar signals are both sent out and then received back. Acoustic communication systems are Sonar devices where there is both a sound wave projector and receiver on both sides of the signal path. The invention of the acoustic transducer and efficient acoustic projectors made more advanced forms of Sonar possible.

What was not a new weapon developed during ww1?
Sonar was not introduced in World War 1.
Was SONAR developed during World War 1 to track the location of underwater mines?
True
Who developed the First sonar for World war 2?
The Royal Navy had Asdic for submarine detection. Initially it was quite primitive. I'm thinking Sonar, as such, is more recent than WW2.
Was sonar used in World War 2?
yes
What new naval technology was used in World War 2?
What new naval technology was used in World War 2? The development of the acoustic transducer that converted sound waves to electrical energy enabled rapid advances in SONAR design and technology during the last years of WW1. Although active SONAR was developed too late to be widely used during WWI, in World War II it was used a lot. The British Anti-Submarine Detection and Investigation Committee nicknamed ASDIC, became a name commonly applied to British SONAR. The use of ASDIC proved pivotal in the British effort to repel damaging attacks by German submarines. The Germans developed a rubber coating (Anechoic) for their U-boats. It had multiple purposes, but its main purpose was to try and absorb sonar waves so the U-boats would be stealthier and less visible to Allied sonar. The coating also, to a lesser extent, made the U-boats quieter when underwater so that Allied ships listening for underwater sounds were less likely to hear the sounds of their onboard machinery etc. It also didn't return as load of an echo from Allied sonar as did a plain metal hull. The Aircraft carriers replaced battleships as the centrepiece of naval warfare doctrine. The Americans had lots of battleships in WWII, but used them mostly as floating anti-aircraft platforms. Some say the aircraft carrier was responsible for the defeat of the Japanese. that's not all of them but its a few, please try and donate more!
When was sonar invented?
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.
What was not a new weapon developed during ww1?
Sonar was not introduced in World War 1.
What is radar and sonar originally developed for?
military just before WW2.
What are the original techneques for sonar systems developed for?
Detection of (enemy) submarines.
What early 1900s development using sound waves made mapping the topography of the ocean floor easier?
SONAR, which was developed by the military to detect submarines.
Was SONAR developed during World War 1 to track the location of underwater mines?
True

The Royal Navy had Asdic for submarine detection. Initially it was quite primitive. I'm thinking Sonar, as such, is more recent than WW2.
Why was SONAR invented?
sonar was discorvered in 1840 the early sientist Sarah Nolsoc. but first used by Samantha Layor
How is war technology used now?
lazors, GPS, radar, and sonar are all examples of things developed for war that are used today
