 TABLES 574-592.— REFLECTION AND ABSORPTION OF 



RADIATION 



According to Fresnel, the amount of light reflected by the surface of a trans- 



parent medium = ± (A + B) - 5 < . ). — f + ;. — f V ■ A is the

amount polarized in the plane of incidence ; D is that polarized perpendicular 



to this ; i and r are the angles of incidence and refraction.
