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?

  • physics -

    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.
