Abstract
For reflection at interfaces between transparent optically isotropic media, the difference between the Brewster angle of zero reflectance for incident -polarized light and the angle of minimum reflectance for incident unpolarized or circularly polarized light is considered as function of the relative refractive in external and internal reflection. We determine the following. (i) for all values of . (ii) In external reflection , the maximum difference at . (iii) In internal reflection and , at ; for , , and as . (iv) For , the intensity reflectance at normal incidence is in the range , , and . (v) For internal reflection and , exhibits an unexpected maximum (= 12.30°) at . Finally, (vi) for , at is limited to the range .
