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.
Is true of the Doppler effect?
the Doppler effect involves moving objectsthe Doppler effect involves moving objects
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.
Does the Doppler effect occur when the observer is moving and the source of sound is stationary?
The Doppler effect is observed when the straight-line distance between the source and observer is changing.It makes no difference which one thinks it is stationary and which one thinks it is moving, and there is no pointin starting that argument. The fact is that each of them is moving in the other's frame of reference, and that isthe only statement that can apply truthfully to the situation.
The apparent change in frequency as a wave source moves in relation to the listener is called?
The Doppler effect is that apparent change of the frequency of a moving object when someone is stationary. A car may seem to get louder as it gets closer to a person and then the sound will drop as the car gets away.

Doppler effect.
What is an example for Doppler effect?
Stars, which are constantly moving away from Earth, have a red tint to them because of the Doppler effect. Also, think of a car moving past you. If you're standing stationary on a sidewalk, and you hear a car approaching, passing, and then moving away from you, the pitch of the engine changes. This is also because of the Doppler effect.

Why dont you notice the Doppler effect for a slow moving train?
The Doppler effect occurs whether the sound source or the listener is moving. You wont notice the Doppler effect on a slow moving train because the radio wave is reflected, its frequency changes depending on the speed of the object.
Who discovered the Doppler effect?
Christian Doppler did not invent Doppler Radar. He described what is now known as the Doppler effect in 1842 in Austria. It is used to describe the behavior of waves (such as light or sound) that are emitted by a moving object. Doppler radar, which utilizes the Doppler effect, was developed in the United States during World War II.
The changing sound of a moving fire engine is the result of?
The Doppler effect.
Which term describes an apparent change in frequency of sound waves of rapidly moving objects?
Doppler effect
How is the Doppler effect used in astromomy?
It is used to determine whether an object is approaching us, or moving away from us. It turns out that - as can be seen from the Doppler effect - most galaxies are moving away from us. In other words, the Universe is expanding.
What is the Doppler effect on sound?
The Doppler effect is a phenomenon observed whenever the source of waves is moving with respect to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for the observer and the source are approaching and an apparent downward shift in frequency when the observer and the source is receding. The Doppler effect can be observed to occur with all types of waves - most notably water waves, sound waves, and light waves.
