Cosmology Redshift Calculator

The light traveling from the supernova towards Earth is stretched because the universe is expanding and so space also expands. The stretched light's wavelength is shifted towards the red part of the spectrum and this phenomenon called cosmological red shift. Enter the observed and emitted wavelength in the cosmology redshift calculator to find the redshift value.

The shift that occurs due to the expansion of the universe is called as the cosmological redshift which can be calculated using observed wavelength and emitted wavelength using this online cosmology redshift calculator.
