The apparent change in the frequency of a sound emitted by a moving object?
Is called Doppler Effect
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary abserver?
That would be the Doppler Effect.
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the what effect?
Doppler effect.
What range of frequency of sound do coal trains emit when moving?
The range of frequency of sound that coal trains emit when moving hovers around 20 Hz to 20,000 Hz
A low frequency sound is produced by a sound wave that?
An object vibrating relatively slowly produces sound waves that have low frequency and long wavelength.

How are radio waves used to find the speed of a moving object?
By using an phenomenon called the Doppler Effect, which causes waves (e.g. radio, light, sound) that are reflected off a moving object (or emitted by a source on a moving object) to shift frequency proportionally to the speed of the object.if the object is moving towards the observer the waves shift to a higher frequencyif the object is moving away from the observer the waves shift to a lower frequencyThe speed detector (e.g. RADAR gun) uses a method called heterodyning to "beat" the original transmitted radio waves with the received radio waves that reflected back from the object to generate a "difference frequency" that will be proportional to the relative speed of the object to the observer. This "difference frequency" is then fed to a frequency counter circuit and the result is scaled to be displayed in the correct units of speed that the user needs. For objects that emit the waves themselves (e.g. stars, galaxies) it is necessary to find spectral lines of known elements or compounds and measure how much the frequency of these spectral lines have shifted from their known standard frequency. If sound waves emitted by a vehicle (e.g. train whistle) you must somehow know the frequency of the sound source on the vehicle when it isn't moving (this may or may not be possible).
What range of frequency of sound do coal trains emit when moving?
The range of frequency of sound that coal trains emit when moving hovers around 20 Hz to 20,000 Hz
When the frequency of sound waves matches the natural frequency of an object the result can be?
the result is resonance
What happens if a sound wave is compressed?
it is unclear what you mean. One form of 'compression' would be the dopplar effect whereby a object producing sound is moving towards the listener. The sound heard by the listener is of a higher frequency than the sound that is produced.
A low frequency sound is produced by a sound wave that?
An object vibrating relatively slowly produces sound waves that have low frequency and long wavelength.
How do vibrations affect sound?
a vibrating body produces sound. ie only if an object vibrates will it produce sound. the faster the object vibrates, the louder the sound and vice-versa. the no of vibrations per seceon is called frequency. thus if an object has a higher frequency, then it produces a louder and shriller sound...
What property of sound changes due to Doppler Effect?
The frequency of any wave system, sound or electromagnetic, will be changed by the source object moving towards us, or away from us. Ascending Doppler shift for those approaching us, descending pitch for those departing.
What causes the frequency of light from a moving object to change?
It is the Doppler effect that causes the apparent shift in the frequency of light or sound waves as the source and observer are moving farther apart or closer toward each other. Use the link below for more information.
Can sound stop a moving object?
Yes, as sound can cause force.
