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).

∙ 13y agoSONAR is the technology that the Navy uses for Sound Operated Navigation and Ranging.
Ranging, or measuring distance with sound, is the part that has to do with your question.
SONAR is used underwater, where speed of sound is more consistant than in air, and where sound itself can travel many times farther than can sound in air.

∙ 14y agoSound waves can be used to measure distance because the waves bounce off a surface, and the time the wave takes to return can calculate the distance away the object the wave bounced off is. Research "Ultrasound" for an example.

∙ 14y agocertain sound wave frequencies travel at a certain speed, thus if we measure the time it takes for a sound wave to hit an object and bounce back, we can measure the difference using the formula: time*speed/2. radar and echolocation both work along these lines.

∙ 13y agoBounce the signal off of a barrier and measure the time it takes to get back. The distance that you want to measure we will call d, but the wave has to travel 2d (there and back).
Thus, v=c=2d/t, rearrange for distance,
2d=ct -> d=ct/2, where c is the speed of light.

What are three features of sound waves?
Wavelength; this is the distance from the crest of one wave to the crest of the next.Frequency; this is the number of waves that pass a point in each second.Amplitude; this is the measure of the amount of energy in a sound wave.
What tools are used to measure sound?
an oscilloscope is used to measure sound waves
Scale that measures amplitude of waves?
That depends a lot on the type of waves you want to measure. For waves on water, you would measure the amplitude in meters, for sound waves you would use pressure units, for electromagnetic waves you would use either electric or magnetic units, etc.
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.
Why do sound waves travel worse through air?
sound waves does not travel through long distance because in sound waves particles vibration is parallel to the direction of wave propagation due to this one particle is collide with other particle so because of this back and forth vibration sound waves travel worse through air

What does the speed of sound measure?

Ways to measure sound from an distance?
to measure sound from distance use decibels
What tools are used to measure sound?
an oscilloscope is used to measure sound waves
An oscilloscope can be used to produce visible pictures of sound waves. If an oscilloscope is used to measure the distance between the crests of a sound wave what property of the wave will it be measu?
Wavelenght
How do you convert meters to KHz and what is 300 meters in KHz?
You do not. A metre is a measure of distance, a kiloHertz is a measure of frequency. The two measure different things and it makes no sense to convert from one to the other without additional information - for example: whether you are talking about electromagnetic waves, or sound waves, or waves in the ocean or whatever.
Scale that measures amplitude of waves?

The waves which can be propagate a long distance through cast iron?
Sound waves.
Why is an oscilloscope used to measure sound waves?
An osciloppe measures oscillations. Oscillations are vibrations. And vibrations are sound waves.
What are three aspects of sound waves?
Three aspects of sound waves are frequency (pitch), amplitude (loudness), and wavelength (distance between wave peaks). These factors determine the characteristics of a sound wave such as how high or low the pitch is, how loud the sound is, and how the wave propagates through a medium.
What scientists use to measure sound waves?
Peguins
