If the speed of light through material Z is
2.5×10^8 m/s, what is this material’s index of
refraction? The speed of light in a vacuum is
3 × 10^8 m/s.

  • Physics -

    n=c/v

    where
    n =the index of refraction
    c =the speed of light in vacuum
    v =the speed of light in a medium

    find n
