What sends sound waves through water?
the sonar
What can A sonar device that uses the echoes of the ultrasound underwater find?
it measures the depth under water
What is the differences of an active sonar and passive sonar?
Active sonar sends a signal out from a source and when it encounters an object the signal reflects back to the source. This can be detected by the object it is reflecting off of like a ship or submarine. Passive sonar is simply putting a microphone in the water and listening. It is also undectable.
Can sonar be used out of water?
sonar can not be used outside water it is used under water to transmit sound waves through ultrasonic pulses
How does sonar system measure distance?
Sonar works by sending a pulse of ultrasound through water. It then listens and detects the pulse if it reflects back from a surface. The time is measured (electronically) between sending the pulse and hearing the retured echo. Knowing the speed at which sound travels through water, it can be calculated how far the returned echo has travelled and hence distance of the object.

How does sound transmitted under water?
it is used my SONAR. When something is underwater. I.E fish. The sound sends a frrequency to the fish, and it bounces back off the fish back to the SONAR. and thats how people know where to go and how to find stuff underwater
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.
Sonar measures underwater distances by using what?
Using the speed of sound in water (about 1500m/s in the sea, depending on the specific sea-water density). So if there is a delay of 2 seconds between a depth-sounding sonar emitting a pulse and detecting its echo from the sea-bed, the water is 1500 X 2 = 3000m deep.
What Is A Good Sentence For Sonar?
If you go under water, you might see a sonar

Can you give an example of SONAR?
A sonar is Fitted into a ship to detect how deep the water is
Can sonar be used out of water?

Does sonar uses sound waves to measure water depth?
Yes. Active sonar generates a pulse, the echo is heard some time later. The time it takes for sound to travel from the generator to the reflector and back to the sensor discloses the distance from the sonar equipment to the object reflecting the sound waves. Passive sonar just listens and does not generate any sound pulses itself but through various analysis algorithms certain information about the distance to an object that does make sound can be obtained. Passive sonar is not used for finding the depth of water but for listening to ships.
