GEOMETRICAL OPTICS


Index of refraction


Fresnel formulas - refraction and reflection - light polarized in the plane of incidence


Fresnel formulas - refraction and reflection - light polarized in the plane perpendicular to the plane of incidence


Fresnel formulas - refraction and reflection - unpolarized light


Brewster's angle


Time of transit of the light


Fermat's principle

Fundamental laws of geometrical optics
1. Law of rectilinear propagation of light
2. Law of mutual independence of the component parts of a light beam
3. Law of regular reflection
4. Law of regular refraction

Corollaries of the laws of reflection and refraction
1. The incident and reflected rays are equally inclined to any straight line tangent to the surface at the point of incidence
2. The projections of the incident and reflected rays upon any place containing the normal make equal angles with the normal.
