As mentioned, POV only does Lambertian diffuse reflection, MegaPOV also 
has a blinn highlight model. POV specular reflection(not highlights) is 
constant, MegaPOV has angle dependant and Fresnel reflection models.

Mostly in lighting.c.

Depends on what you mean by "scientific-grade". POV is often used to 
produce images for visualization, and the scene language can do some 
simulations. However, there are many features that are not based on 
reality...so if you use these, forget about doing a simulation of real 
light.
