just a few quick communication questions...
1-is it possible to have total internal reflection for light incident from air onto water? why?
2-what is the angle of refraction when a light ray meets the boundary between two materials perpendicularly?
1. No. The refracted angle would be 90 deg, so
In Texas, sines don't go that high.
2. Perpendicular goes straight thru, no bending.
