How the snell's law come?

    what is the snell's law?

    and how to show this
    n = sin(i)/sin(r)

    n = refractive index
    i = angle of incident
    r = angle of refraction )

    thank you!

    Or you can just solve Maxwell's equations with appropriate boundary conditions.

    Maxwell's equations on EM Waves will provide the most elegent proof of Snells Law, Laws of Reflection and all the rest. You can read it from David Griffits "Intro ...to Electrodynamics".
