How would you detect a soundwave?
The human ear can detect sound waves, but it has limited range and sensitivity. Some might chose to use a microphone and an associated electronics package to detect sound. Sound that is too soft to be detected or at too high or low a frequency to be heard might be looked at on a screen where the sound picked up by the microphone is amplified and converted to a picture that is displayed to provide a visual representation of the sound. ...
What things can be used to detect invisible forms of electromagnetic radiation?
Different devices are used to detect different frequency ranges of electromagnetic waves. You simply can't use the same device to detect x-rays, than you would use to detect radio waves, for example. ...
Asked in Electricity and Magnetism
What instrument uses magnets to create sound waves?
An electric guitar and some old organs and keyboards use magnets wrapped with fine wire to detect movement in the field. In an electric guitar that would be the guitar string moving near a pickup. It makes electricity which is amplified. ...

What are uses of sound waves to measure distance?
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 are sonograms produced?
Sonograms are used to look at things inside the body including organs, blood vessels, bones, and fetuses. They are basically sound waves that are reflected off of different tissues. They are then received and displayed on a monitor. It works in much the same way RADAR is used to detect aircraft that are in the air, except they use sound waves instead of radio waves. ...
What part of the electromagnetic spectrum do sound waves use?
Sound is a mechanical vibration and not an electromagnetic one. The electromagnetic spectrum is reserved for electromagnetic waves and will not have a place for sound on it. ...
Asked in Earthquakes, Volcanoes, Predictions
Which instrument is used to predict earthquakes and volcanic eruptions?
A strainmeter is used to predict earthquakes and volcanic eruptions by the coordinated use of the seismometer to detect the earthquake's or eruption's underground vibrations or shock waves that the seismograph records. ...
