Does light get red shifted during lensing, when it passes by an object with great mass such as a galaxy or cluster?
If so then what are the effects on measurements of the CMBR and most distant red shifted galaxies?
If true then presumably some light would be red shifted more than others resulting in frequency dispersion?
