Refractive index----- will it travel back along the same way?
From the picture
http://en.wikipedia.org/wiki/File:RefractionReflextion.svg
If I travel a light ray from n2 to n1 , I think the light ray will travel in the opposite direction shown in the first picture.
But what about the second? The light that 90 degree will find the same way back? I think it should go straight? How should the light travel and why?
Thanks
