A galaxy is observed to have a significant redshift in all of its spectral lines. The line normally seen at a wavelength of 327 nm is instead observed at 360 nm. How far is this galaxy from the milkyway
My approach
All I can calculate here is the red shift based on the formula
Z= observe wavelength- emitted/ emitted
Z= 360-327/327
=0.101
This has nothing to do with distance or does it?
