Form of sonar used to locate enemy submarines by ultrasonic waves?
Due to their short ranges, ultrasonic (>20khz) frequencies aren't used for ship or submarines' primary Active Sonar systems. Though the actual frequencies used are classified, I can say that they're nowhere near the ultrasonic range. Submarines do employ ultrasonic frequency detection systems that are passive sonar based, but they're primarily for detecting active sonar from homing torpedoes. They're also annoying for detecting any bottle-nosed dolphins in the area when you're at Periscope Depth.
How do submarines detect enemy ship at sea?
By an electronic device called 'sonar' .
How were sonar systems used in World War 2?
They were used by submarines to navigate when not in open waters, They were also used by submarines and anti-submarine ships to locate enemy submarines.
Why is water a good medium for communication between dolphins?
Sound waves travel very well in water. Warships, including submarines, use passive sonar to listen for enemy ships and submarines. Passive sonar employes underwater hydrophones to listen for sounds. They can detect sounds of ships and submarines miles away. Marine mamals such as whales and dolphins detect sound in much the same way.
How can submarines detect other submarines under water?
The main method is through listening using passive Sonar. Active sonar sends out a sound signal that can be used to bounce off the enemy. It may also give away their own position.
How did sonar help in World War 2?
Sonar was used widely in World War II in an effort to locate enemy submarines. It wasn't as sophisticated as it is today, but it did help. Actual numbers are difficult to come by, but sonar was effective in the successful attacks on several submarines.
What is the technique used by submarines to locate their enemies?
They use sonar to find the enemy. Passively, they listen for the sounds of the other ships, which will give them a bearing to the target. Active sonar will ping the enemy and provide a range as well.
What is the basic purpose of a MODERN submarine?
There are now 'Attack' submarines who's main purpose is to sink enemy submarines and ships and also Missile submarines whose main purpose is to launch ballistic missiles at the enemy.
How was the submarine used in 1919 in the great war?
By torpedoing their enemy ships: it was all they could do and were designed to do; but anti-submarine warfare was in its infancy and submarines were very hard to detect once submerged. They are even stealthier now.
Why did they use the subs in war?
To sink enemy vessels, ships or submarines.
What are the original techneques for sonar systems developed for?
Detection of (enemy) submarines.
What did the military use sonar's for?
Sonars were used to detect any objects that got into the detection field of the sonar. By this, the military could detect enemy submarines etc., which they couldn't see normally because of the opacity and/or darkness of the water.
