When a light source is receding away from an observer then due to Doppler effect the frequency would appear to fall. Hence the colour would be shifted towards the red end. Hence red shift
Same way as the source is apporaching the observer, then frequency would appear to increase and so it moves towards violet. Hence violet shift.
One of the most reliable methods employed presently is using Hubbles Laws and Constant, utilizing the red shift. RED SHIFT A+LS (:
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).
Doppler.
The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
Red shift does not support the steady state theory.
The opposite of the red shift is the purple shift.
The Red Shift was created in 2005-06.
One of the most reliable methods employed presently is using Hubbles Laws and Constant, utilizing the red shift. RED SHIFT A+LS (:
It is the Doppler effect that causes the apparent shift in the frequency of light or sound waves as the source and observer are moving farther apart or closer toward each other. Use the link below for more information.
This phenomenon is called red shift.

Red shift has confirmed the expansion of universe. Both red and blue shift at the edges of the sun has confirmed the spin of sun..
In 1848, Hippolyte Fizeau first noted a red shift in stars. In 1912, Vesto Slipher first noted a large red shift in nebulae. In 1929, Edwin Hubble published his findings that the size of galaxy's red shift was proportional to its distance from our Earth.
