Snell's law

  1. Jun 29, 2012 #1
    Hi people..

    Snell's law reads sinθ = (v2/v1)sinβ

    Suppose that v2/v1 > 1, then we can make sinβ as close to 1 as we like, even close enough to make sinθ>1 as Snell's law states.

    So what's wrong?

    Hi Mohammad_93! :smile:

    (try using the X2 button just above the Reply box :wink:)
    In that case, θ does not exist, and there is total internal reflection. :wink:

    Try to be consistent with your notation.
    Snells law is written as
    Sinia/Sinib = va/vb
