Homework Help: Refractive Index Units - -

    Refractive Index Units - URGENT -

    1. The problem statement, all variables and given/known data

    Does the Refractive Index of a medium have units. If so what are they? i am needing this for a lab report - so i can quote answers and feel fine that i am not giving any units. I am pretty sure there arent any.

    No they do not have units as they are a ratio of velocities or wavelengths or sine's of angles.
