A piece of gallium phosphide is frozen in ice. a beam of light is directed downward through the ice-gallium phosphide boundary at a 25 degree angle from the normal. The light emerges from the gallium phosphide 12.25 mm away from where it would have had the solid been pure ice. Find the thickness of the gallium phosphide layer. Gallium phosphide has the highest known optical density (3.5), and ice has the third lowest (1.31).
I know this question is supposed to be easy in that we need to apply snell's law. but can someone please draw an image of what it looks like... because i have no idea what they are asking... is the ice layer on top of the gallium layer...
