Who discovered the Doppler red shift?
The Doppler redshift was discovered by Hippolyte Fizeau in 1848.
Who developed the red shift method?
Christian Doppler, and Austrian Physcist .
A Doppler red shift indicates?
a star is moving AWAY FROM EARTH
The Doppler shift can be observed when?
When an object moves away from us, or towards us.
How are Doppler blue and red shift different?
A blue shift is observed in the spectrum from an object approaching the observer whereas a red shift is observed for a receding object.
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
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.
The apparent shift in the spectrum of a star as it moves toward or away from the earth is explained by the phenomenon known as the?
Doppler effect. This effect causes the wavelengths of light from a star to appear shorter (blueshifted) as it moves towards the Earth and longer (redshifted) as it moves away, providing valuable information about the star's motion in space.
