What does a blue and red shift of absorption lines in a spectrum indicate?
Blue shift is a decrease of a signal's wavelength, and/or an increase in its frequency, due to the Doppler Effect. This indicates that the object is moving towards the observer.Red shift is the increase of a signal's wavelength, and/or a decrease in its frequency, due to the Doppler Effect. This indicates that the object is moving away from the observer.
Would a light source moving away from Earth appear blue shifted or red shifted?
A red shift indicates an object that is moving away from the observer, and a blue shift indicates an object that is moving toward the observer. Both of these are called Doppler shifts.
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 .
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 does the amount of red Doppler shift indicate?
It indicates how fast an object is moving away from us.
What are the best indications that the universe is expanding?
A misunderstanding of red shift is the indicator is expanding. The correct understanding of red shift indicates the universe is in continuity, not expanding and is finite. RED SHIFT OF DISTANT GALAXIES.

What effect is red shift an example of?
The Doppler effect.

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 is an explanation of the Doppler shift?
The Doppler Shift is a change in frequency due to the Doppler Effect.
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 it called when galaxies move away and the light waves become longer?
That is called a red shift or a Doppler shift.
How did the Doppler effect lead to the Big Bang theory?
Actually, it wasn't the Doppler-effect that lead to the Big Bang theory, but the red-shift of remote galaxies. Although it was initially thought that this red-shift might be caused by a Doppler-effect, it is now understood that this red-shift is caused by the metric expansion of space itself.
