when a luminous source is relatively moving away, the light emitted from the source is almost stretched (the frequency of the waves decrease). In other words, enough redshift will cause violet light to become red due to a decrease in frequency. Light which is already red will turn to infra-red, microwaves, and radio waves. If the redshift is very very very high (this does not usually happen in the universe), even x-rays and gamma-rays can be red shifted to radio waves.
Similarly, when the source is moving relatively closer, the light emitted will be blue shifted: the frequency will increase.
This is called the Doppler shift or the Doppler effect.

What would red shift do to helium's Fraunhofer lines?
The location of those lines would be shifted to a longer wavelength (or lower frequency or energy) -- ie, towards the red part of the visible spectrum. In other words, a red shift.
What is important about Hubble's discovery that there is a red shift the spectra of galaxies?
It is difficult to estimate the distance of astronomical objects without information about its intrinsic brightness. However, its spectrum will contain absorption lines based on elements, such as hydrogen and helium, in the outer regions of the object. This lines are characteristic of the elements and they are also red-shifted which allows the red shift to be measured more readily. The red shift is a measure of how fast the object is receding from the earth and, because the red shift is correlated with the distance from the earth, it provides a relatively simple guide to the distance of the object.
The spectral lines of elements when observed in distant galaxies show a shift towards?
The red end of the spectrum.
Does the velocity of a star toward or away from earth determine measuring the shift of its spectral lines?
Yes. If the star is moving away from the Earth, its spectral lines will shift towards the red end of the spectrum. If it is moving towards the Earth, its spectral lines will shift towards the violet end of the spectrum. This is due to Doppler effect.
How do you make backwards turbo lines online rider?
To make backwards "Turbo" lines in line rider, you hold shift and make a backwards red line.
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
How do you calculate red shift?
The spectrum of light emitted from heated hydrogen has dark lines, caused by the absorption of a very narrow wavelength band of light. These dark lines always take the same location relative to each other. If all the lines in an object's spectrum are shifted by the same amount, towards the red end of the visible spectrum, then the light is "red shifted." The amount of the shift is often described with a number 'z', where z equals the shift in wavelength divided by the wavelength as originally emitted by the object.
When was The Red Shift created?
The Red Shift was created in 2005-06.
What determines galaxy motion and distance?
One of the most reliable methods employed presently is using Hubbles Laws and Constant, utilizing the red shift. RED SHIFT A+LS (:
What is the shift in the light of a galaxy toward the red wavelength called?
This phenomenon is called red shift.
What does it mean when an astronomers observing starlight wa spectrograph notices shift at off lines to the red end of spectrum?
The star is moving away fro where it is. ~Justine... :))
What is the red shift of hydrogen?
The red shift depends on the relative motion of the emitting source and receiving detector. Hydrogen per se has no red shift. There is hydrogen with great red shift (in stars in galaxies far away that are moving rapidly away from us).
