Homework Help: Modern Optics

  1. Oct 29, 2013 #1
    Hi And Need Help
    The main Question is what happens to light and cause go into next medium as total internal reflection happens for incident angles higher than critical angle ?
    so the main question is why the light path throughout the second medium?
    We know when light travels from a medium with a higher refractive index to one with a lower refractive index, according to Snell's law light in such cases is completely reflected by the boundary to the first medium, a phenomenon known as total internal reflection. so the main question is why the light path throughout the second medium?
    My main propose is to achieve a physical interpretation of this paradoxical duality .
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    At internal reflection, the light does not travel in the second medium, but there is an electric field there in the form of exponentially decaying standing wave.
