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.
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!

They determine it by using sonar.
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.

they use SONAR. :)

sonar(sound navigation and ranging)
Sonar location is in the water and echo location is in the air.
It will depend on the speed of sound in the medium. Sonar is often used for underwater location and the speed of sound through water is quite different from the speed of sound through air.
That right there is sonar.
