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.

What is the correct definition of sonar?
1. A system using transmitted and reflected underwater sound waves to detect and locate submerged objects or measure the distance to the floor of a body of water.2. An apparatus, as one in a submarine, using sonar.3. Echolocation.http://www.thefreedictionary.com/sonar
A sonar system measrues distance by determining the?
time it takes for sound waves to bounce off a surface
How can we measure the depth of sea by using SONAR?
Simply by measuring the time it takes for the sonar 'ping' to return to the device that sent it. The speed of sound is constant - and dividing the time by the speed of sound gives the distance !
What instrument emits a sound wave to measure the ocean floor?
sonar
What instrument measure the depth of the ocean using sound waves?
'Sonar". And determines depth. The ocean floor topography can be mapped by 'sonar scanning'.
The system of using sound to measure distance is called what?
Sonar.

What is sonar in a scientific definition?
SONAR stands for SOund Navigation And Ranging.SONAR is a device that uses ultrasonic waves to measure the distance , direction and speed of underwater objects.
What does sonar measure?
Sonar is measured in sound
What system is used to measure distance in Brazil?
The metric system is used to measure distance in Brazil.

How distance measured?
-- ruler -- tape measure -- surveyor's walking wheel -- meter stick -- surveyor's chain -- odometer -- laser rangefinder -- radar -- sonar

How do you measure the depth of a undersea wreck?
With sonar
In the metric system what would you measure in meters?
distance
What scientific instrument can be used to measure the length and width?
ruler, caliper, tape measure. In today's high tech world, there are also laser/sonar devices too. The laser beam is pointed to a hard surface and then the sonar sends and receives a signal - based upon the time interval, the exact distance is computed.
