What is an explanation of the Doppler shift?
The Doppler Shift is a change in frequency due to the Doppler Effect.
What is the change in frequency of a sound due to motion of the source?
The change in frequency is caused by the Doppler Effect
Does the Doppler effect only apply to sound waves?
No
How can laser Doppler velocimetry be used?
Laser Doppler velocimetry also known as Laser Doppler anemometry, is the technique of using the doppler shift to measure the velocity in transparent fluid flows reflecting surfaces.
Doppler effect states that the motion of any object can?
Shift the wavelength of the spectrum.
What is an explanation of the Doppler shift?
The Doppler Shift is a change in frequency due to the Doppler Effect.
What is the change in frequency of a sound due to motion of the source?
The change in frequency is caused by the Doppler Effect
How can you use Doppler shift in a sentence?
Doppler shift is the change in frequency of a wave that seems to occur as it moves. Scientists study the doppler shift to see whether stars are moving away from or toward our galaxy.
What is the wavelength shift caused by local motions?
Doppler shift
What do Doppler shift observations of a spectroscopic binary star enable astronomers to calculate?
They let us see the speed of the stars around the common center of mass. More precisely, the Doppler shift will only detect the component of this speed in our direction - that is, towards us, or away from us.
Who discovered the Doppler red shift?
The Doppler redshift was discovered by Hippolyte Fizeau in 1848.
Why would a passing race car display more Doppler effect than a passing police siren?
The amount of Doppler shift depends on speed - the faster vehicle will show more Doppler shift.
What is a Doppler red shift and a Doppler blue shift?
A Doppler red-shift is a shift in recognizable features of a star's spectrum from the wavelengths where we know they belong toward longer wavelengths. Such a shift can be caused by the star's moving away from us, and that's how it's interpreted when astronomers see it. A Doppler blue-shift is a shift in recognizable features of a star's spectrum from the wavelengths where we know they belong toward shorter wavelengths. Such a shift can be caused by the star's moving toward us, and that's how it's interpreted when astronomers see it.
What effect is red shift an example of?
The Doppler effect.
Does the Doppler effect only apply to sound waves?
No
Why is there no Doppler shift when a star is moving tangentially?
Because there is only a shift if the object's distance is changing.
Does a star that shows no Doppler shift move?
If there is no observable Doppler shift, then the star is probably not moving very fast. This refers to the component of the star's movement toward us, or away from us - the "sideways" part of the movement can't be determined by the Doppler effect.
