Our ears are designed to hear sounds traveling through air. When these sounds are made underwater, they travel at slower speeds, causing them to bounce off surfaces differently and sound differently.

What is the technology that uses sound waves to find objects under water called?
SONAR (sound navigation and ranging)
How SONAR is made?
Depends on what type of sonar as in the technology used by navy to identify under sea contacts then: A sonar is a method of detection most commonly used by the navy. It works by emitting a sound into the water of which goes down and when it hits something it bounces off that object and will return to the emitter of which is timing the time between the creation of the sound and the receiving of it. This time is the easiest way of identifying the depth of the object. In there simplest form they are a speaker a microphone and a electronic timer oh and some water. 1) Release a sound into the water whilst starting the timer which is rigged to turn off when the microphone receives the sound. 2) wait for the sound to bounce off an object or the sound to hit the bottom of the object holding the water. 3) as soon as the microphone receives the sound the timer will shut down and you will know the distance of the object after you convert the time to distance.
How does sound move through water easily?
because there are more particles in water than air but there are more in solids than water so sound travles further in solids than liquids ore air
How is sound used to locate objects?
Echo location: You send out a directional high frequency sound. The sound bounces back in a slightly different way and at a slightly different time from different objects at different distances. You detect the differences with your Echo Locator device and that's how you can locate where objects are and how far away they are. Examples: Its how SONAR on a Navy Destroyer or Helicopter SONAR Pod detects submarines under water. Its how a fishing boats "Fish Finder" works. (A kind of SONAR) This is how BAT's fly at night or in the dark. (Very high pitched squeaks) Its how Dolphins locate prey to eat and how they detect things in murky water.
Disadvantages and advantages of submarine cables?
A. you can go under water. D. if they break you die.
How does sound waves in ocean help dolphins communicate?
When sound originate in the water, the sound waves tend to refract down, toward the cooler water.
Does a pool of water reflect or refract?
refract
Does water refract light?
Yes, it does refract light.
Why is the land hotter than water when exposed under the sun?
Land is hotter than water when exposed to direct heat under the sun because of its density. It holds in heat and cannot refract it the way that water can.
How does water refract light?
it doesn't.
What do you need to refract light?
Water
How do water wave refract?
craziness
Does water refract or reflect light?
Both
which of the following does not refract light?
glass of water
Why can't sound travel under water?
Sound does travel under water otherwise the Humpback would be wasting its time singing!
What is the sounds of a yacht?
When under power the sound of the engine and water lapping at the hull. When under sail the sound of water lapping at the hull.
When light moves from air to water the light will?
Refract
