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.

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 technique for determining the distance of an object under water is called?
Sonar is a common technique used for determining the distance of an object underwater. It works by emitting sound waves and measuring the time it takes for the waves to bounce back, which allows calculation of the distance based on the speed of sound in water.
A sonar systems measure distance by determining the?
time it takes for sound waves to travel to an object and back. By calculating the round-trip time and knowing the speed of sound in water, the distance can be accurately determined.
A sonar system measrues distance by determining the?
time it takes for a sound wave to reflect back from an object. By calculating the round-trip time and knowing the speed of sound in a particular medium, the sonar system can accurately determine the distance to the object.
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.
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 is used to locate objects under water by the reflection of sound waves?
Sonar, which stands for Sound Navigation and Ranging, is used to locate objects underwater by sending and receiving sound waves. The device measures the time it takes for the sound waves to bounce off an object and return to the source, allowing for the calculation of the object's distance and direction. Sonar is commonly used in various applications such as navigation, fishing, and oceanographic research.
How does sonar detect water?
Sonar works by emitting sound waves into the water that bounce off objects and reflect back to the sonar device. By measuring the time it takes for the sound waves to return, sonar can determine the distance to the objects and create a picture of the underwater environment.
What do sonar and radar have to do with light waves?
Sonar and radar are both used for detecting objects and determining their distance by sending out waves and measuring the time it takes for the waves to bounce back. While radar uses radio waves, which are a form of electromagnetic radiation with longer wavelengths, sonar uses sound waves, which are mechanical vibrations that require a medium to travel through. Both techniques operate on the principle of wave reflection to gather information about the surrounding environment.
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.
How far away can sonar kill you?
Sonar does not have the ability to kill humans, regardless of the distance. Sonar is a technology used for detecting objects underwater by emitting sound waves, but it does not have the capability to cause harm or kill living beings.
What is the importance of latitude and longitude?
Latitude and longitude are important for determining specific locations on Earth's surface. Latitude measures the distance north or south of the equator, while longitude measures the distance east or west of the Prime Meridian. Together, they provide a precise way to pinpoint any place on the planet.
