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.
A red shift in the spectrum of the light from an object indicates the object is moving where?
A red shift in the spectrum of light from an object indicates that the object is moving away from the observer. This is a result of the Doppler effect, where the wavelengths of light are stretched as the object moves away, causing a shift towards the red end of the spectrum.
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?
Christian Doppler, an Austrian physicist, is credited with discovering the phenomenon of the Doppler red shift in 1842. He observed that the pitch of sound waves from a moving object changes depending on the object's motion relative to the observer. His theory was later extended to light waves to explain the red shift observed in the spectra of distant galaxies.
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 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.
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.
Does a red shift indicates that objects are moving toward earth?
Red shift occurs when an object moves away from the observer. So as you are on Earth, it is when objects move away from Earth. (Blue shift as it moves closer.) A star's red shift could be due to losing energy to gravity.
What is it called when galaxies move away and the light waves become longer?
That is called a red shift or a Doppler shift.
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
Where is Betelgeuse on Doppler Shift?
Betelgeuse is a red supergiant star located in the Orion constellation. Its light exhibits a small Doppler shift due to its motion relative to Earth, but this shift is not significant compared to its overall distance and size. The Doppler shift of Betelgeuse's light is mainly influenced by its own pulsations and variations in brightness.
