I'm currently retagging all questions tagged light to visible-light and/or electromagnetic-radiation
Since editing them all at once will flood the main page, I'll keep track of them here, and slowly work my way through them.
Feel free to help! (try to do maximum 5 at a time)
Final destination is this synonym: https://physics.stackexchange.com/tags/visible-light/synonyms
No need to vote for it, a mod will synonymify it once the retagging is done.
There now is a userscript for this https://gist.github.com/2994654 (full details here ).
EDIT: the synonym has been created, so the link light doesn't work anymore. Use this Data.SE query instead.
