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.
How does sonar system measure distance?
A sonar system measures distance by sending out sound waves that bounce off an object and return to the sensor. The system calculates the distance based on the time it takes for the sound waves to return. By knowing the speed of sound in water or air, the system can accurately determine the distance to the object.
How does side-scan sonar differ from ordinary soanr?
Side-scan sonar is designed to provide detailed images of the seafloor and objects in the water column by scanning a wide swath to the sides of the sonar device. Traditional sonar, on the other hand, typically provides a single beam that measures the depth directly below the device. Side-scan sonar is often used for underwater mapping and search operations, while ordinary sonar is more commonly used for depth sounding and navigation.
What were the two different types of sonar?
The two types of sonar are active and passive.Active sonar uses a transmitter, a device that converts electrical energy to sound energy, to send out sound waves. The sound waves travel through the water until they strike an object. The object reflects them in various directions. Some of the reflected waves return to the sonar, where they strike a receiver. Sonar determines distances by measuring the time taken for a sound wave to travel from the transmitter, reflect from the object, and travel to the receiver.Passive sonar receives sound waves given off by some other source, but does not transmit sounds. Passive sonar can therefore determine the direction of an object, but is not as effective as active sonar in determining its distance.Hope I cleared your doubt!- Harman Kahlon
What can A sonar device that uses the echoes of the ultrasound underwater find?
A sonar device can detect objects underwater by emitting sound waves and analyzing the echoes that bounce back. It can be used to find underwater features such as fish, submarines, shipwrecks, or the seafloor.
What tool is used for SONAR?
SONAR (Sound Navigation and Ranging) primarily uses sonar systems that include transducers, which emit sound waves and receive echoes. These systems can be categorized into active and passive sonar. Active sonar sends out sound pulses and listens for their return, while passive sonar detects sounds made by objects in the water without emitting sound waves. Common tools used in sonar applications include echo sounders, hydrophones, and sonar arrays.
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.

The system calculates the distance based on the time it takes for the sound waves to return. By knowing the speed of sound in water or air, the system can accurately determine the distance to the object.
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.

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.
