If a light wave is travelling through a anisotropic material what would DELTA n be?

  1. Oct 12, 2014 #1
    I finally understand the principle of being able to imagine light as having 2 perpendicular componants of electric field, to use an analogy from an earlier thread, its just as a weight on a slope may be considered to have 2 componants.

    Anyway, for this example nx = ny = no and nz = ne. Light is travelling in the y direction therefore the perpendicular E componants will be subject to nx and ne i.e. there will be birefringence.

    My question is the question asks for Δn and I am unsure what this means. Do I just find a term for nx - ne?

    Please see attached images to visualise the problem, 1 shows the problem, 2 shows the working for a similar problem, thanks in advance.


    p.s. this is not part of any assessed homework
