Homework Statement
So I'm starting to write a lab report but I've hit a boundary in that I have inflicting opinions on what the plural of 'refractive index' is. I have some people saying 'refractive indices' and others saying 'refractive indicies' and a few people saying 'refractive indexes'. I'm pretty sure it's not the latter but i have no idea which of the first two. Spelling really does matter in this thing.
Thanks in advance
