How is sea beam used?
It maps ocean-floor features, sea beam relies on sonar which is the use of sound waves to detect & measure objects underwater.
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
What are sonar rays?
Sonar is a method of detecting underwater objects with sound pulses-like radar but with sound not microwaves
Which of these uses sound waves to measure the distance between objects underwater?
Sound waves bounce off the ocean floor and come back up to whatever emitted it. The time it takes for the sound wave to come back tells how far down it went. Doing this many times over and over, one can map out the ocean floor, and if the sound wave comes back relatively fast, that means there is something on the ocean floor.
How can you measure distance with sound waves?
Animals such as bats project sound waves at objects and use the time until the perception the reflected wave to determine the distance of the object. This is called echolocation. Humans have used the same principles to develop Sonar technology, which is used primarily underwater to detect objects under water (we have radar and plain sight to detect objects in air).
How is sea beam used?

What is the system that uses the reflection of underwater sound waves to detect objects?
sonar(sound navigation and ranging)
The reason submarines can detect other underwater objects is largely due to which what?
sound wavers are affected by propellers
What does SONAR mean and what is this method use for?
SOund Navigation And Ranging. Its used mainly to detect underwater objects.
How does sonar detect underwater objects?
Sonar is when you send sound waves out. They bounce off of objects, letting people know there is an object there. Dolphins and bats, among other animals, use sonar.
What is the use of sonar?
SOund Navigation And Ranging = SONAR Sound is used underwater to bounce off objects. The reflections back can be measured (by electronics) to find our where they are and how far away. Used by submarines, to navigate round obstacles underwater and detect other vessels.

How can submarines detect other underwater objects?
Underwater objects are usually tracked by means of the sounds given off by an object. For a submarine, sound is generated largely by its propellers as they churn through the water. However, the engines and some other parts also generate noise. These noises are detected by a submarine's sonar (sound detection and ranging equipment).Objects can also be located by reflected sound waves, known as "active sonar". A "ping" or sound wave is generated into the water. Any differences in the returning sound indicates the location of an object or structure underwater. This technique can also be used to map the ocean floor.
How sound waves can be used to find underwater objects?
Sound travels through water. Sound reflects from objects with different densities. You can listen for the echoes.
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.
A devise that bounces sound waves off underwater objects is called?
SONAR (SOund Navigation And Ranging)
How do bats fly without knocking in the objects?
The use sound to detect what is around them. The echolocation sound bounces off objects and then back to the bat.
