True!
Pretty much but it's not always off the ocean bottom. Sonar sends out a spherical "ping" it then receives pieces of the sphere back at different times based on when it hit something. It knows it's not the source as the pitch of the ping changes upon contact with a solid object. To gauge depth like what you're asking about something called "Directional Sonar" is used. Which focuses the ping in a given direction rather than a broad spectrum.

The system of using sound to measure distance is called what?
Sonar.
How can sonar determine the shape and distance of an object?
Sonar measures the distance of an object by sending out a ping and listening to the echo. Sonar on a submarine will have many hydrophone locations to tell the listener the direction of the object, and by measuring how many hydrophones the echo hits, where, and when, you can use math to discover the approximate length of what you are listening to. Modern day sonar will often do the math for you and show you a radar like screen of dots where the sonar has heard an echoing ping within a certain distance. Also, once any specific ship has been heard once by a hydrophone and identified as a certain class vessel, the sonar crew can use passive sonar (no pinging. Listening only) to hear the screws turning in the water and can usually tell the experienced sailor (or the modern computer database) what types of ship it is likely to be. In the movie "The Hunt for Red October" the sonarman on the american submarine heard what the computer called "seismic activity" and identified this as, in fact, the Red October. This first identification, which took some time, enabled him to identify the sub faster in the future. There are however disadvantages to sonar. In modern times almost all military naval vessels have at least some basic form of sonar. As soon as somebody on a submarine sends a ping,, veryone else in the area knows you're there. Some ASW tactics involve planes dropping hundreds of passive and active sonobouys all over the area. The submarine will usually attempt to hide from the active sonobouys which will often lead it right towards a passive sonobouy.
What is a meter used to measure?
it measures length or distance. a meter is 39 inches.
What does sonar equipment measure?
Sonar is the science of sending out sound waves to an object and waiting for them to be bounced back to a receptor. Scientists can use this by shooting out the sound waves, then counting the amount of time it takes for the wave to shoot back to the receptor, and calculating the speed of the wave in proportion to the amount of distance traveled to get an idea of how large an object is. They would need to do so on all sides of it, of course, and it probably helps that they have lots of equipment to help measure.
Which tool measures distance a thermometer pan balance stopwatch or meter stick?
measuring tape,ruler,measuring cup/spoon,lazer
A sonar system measrues distance by determining the?
time it takes for sound waves to bounce off a surface
What are the applications for sonar?
A)to find the depth of the sea b)the sonar device measures the time taken by the ultrasonic sound to travel from the ship to the bottom of the sea .
The system of using sound to measure distance is called what?
Sonar.
How does a camera use Sonar?
A camera uses sonar to detect the distance to the object you are taking a picture of so it can focus the lens properly.
What can A sonar device that uses the echoes of the ultrasound underwater find?
it measures the depth under water
Why cant sonar find the distance between the earth and the moon?
Sonar is a sound phenominon, it requires a liquid (water, air, etc) to work.
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.
Is latitude or longitude more important in determining the type of biome in a given area?
The latitude is the measure of an areas distance from the sun while the longitude is the measure of the angular distance on earth's surface. The latitude measures the climate and therefore the type of biome in a given area.
How is a parallax used in astronomy?
for determining distance
What are the differences between side scan sonar multi-beam sonar?
Side scan sonar uses sonar to map the the ground below by emitting continuous sonar pulses while moving. The sound continuously reflects back to the system's receiver, which creates an image based on the energy of the signal received, where darker points in the image match things protruding from the ground and lighter spots indicate where there is nothing. It does not measure the depth. Side scan sonar is usually towed behind the vessel using it. Multibeam sonar is similar to side scan sonar, except that it is attached to the vessel (rather than being towed) and measures the time difference between sound emission and reception, rather than the energy of the incoming sound waves. Thus, it measures depth instead of making a picture.
What metric unit is used for determining distance?
