Asked by Cynthia
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
Nair*sinThetaincid=Nwater(sin90_
sinthetaincid=1.333
In Texas, sines don't go that high.
2. Perpendicular goes straight thru, no bending.
