what is the snell's law?
and how to show this n = sin(i)/sin(r) (where n = refractive index i = angle of incident r = angle of refraction ) ?? thank you!

You can derive snell's law from Fermat's principle of least time
http://www.physics.yorku.ca/undergra...ch/SNELL3.html Another derivation can be done using Huygen's principle. spacetime www.geocities.com/physics_all/index.html

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

how the snell's law come?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".
