For a swimmer, the line of sight is usually not very far from horizontal, so the angle of incidence is large: well above the critical angle for water, which is 49°. We explore refraction through observing how light bends when an object is placed in water. To get a better idea of how this might work, I drew a simple model in Sketchup and ran the light simulation plugin on it. 1 we introduced the bidirectional reflectance distribution function (BRDF) abstraction to describe light reflection at a surface, the BTDF to describe transmission at a surface, and the BSDF to encompass both of these effects. oPhysics: Interactive Physics Simulations This is a simple simulation showing the reflection and refraction of a ray of light as it attempts to move from one  Ray Optics Simulation.
