Knowing how fast sound travels through water, the time taken for a noise to travel to a target (e.g. a shoal of fish or the sea bottom) and back gives an indication as to how far away the target is.
The speed of sound in water is approximately 1500 m/s, so if an echo returns after 2 seconds then the reflecting object is 1500 m away.

When was sonar first used and by whom?
Sonar was first used during World War I by the British Royal Navy. It was used to detect submarines by emitting sound waves and analyzing the echoes that bounced back.
What is the meaning sonar?
Sonar stands for "sound navigation and ranging." It is a technique used for detecting and locating objects underwater by sending out sound waves and analyzing the echoes that bounce back. Sonar is commonly used in navigation, fishing, oceanography, and military applications.
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.
Sonar is a device for?
sonar is a device for detecting objects underwater by emitting sound waves and analyzing the echoes that bounce back. It is commonly used in navigation, fishing, and underwater mapping.
What words make up the term sonar?
The term "sonar" is a compound word derived from "so" for sound and "nar" for navigation or ranging. Together, "sonar" stands for Sound Navigation And Ranging, a technology used for detecting objects underwater by sending out sound waves and interpreting the echoes that bounce back.
How does sonar use echoes to locate objects?
Sonar uses echoes to locate objects by bouncing sound waves off them and detecting the echoes.
What Are undesired sonar echoes?
Reverberations

Are echoes important?
Yes, echoes are important because they can provide information about the surroundings, such as the size and distance of objects. In nature, echoes are used by animals for navigation and communication. In technology, echoes are utilized in echo-location systems like sonar and radar for a variety of applications.
What is a device used in submarines to navigate surroundings by detecting echoes?
This sounds like it's probably the sonar system of a submarine.

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.
What is the medical procedure called that uses echoes to inside a patients body?
sonar
What is sonar and how does it detect aeroplanes?
Sonar is the generic name of the technology that is used to locate objects underwater. Sonar systems are of two basic types - active and passive. In active sonar the system let's out a pulse of sound and then the operator listens for echoes. The passive sonar the operator listens to sounds emitted by the object one is trying to locate.
