Preferred Label : reflectance;
Detailed label : reflectance, ρ;
IUPAC definition : Fraction of incident radiation reflected by a surface or discontinuity, ρ λ P λ
refl P λ 0, where Pλ0 and Pλrefl are, respectively, the incident and reflected spectral
radiant power.;
Scope note : the reflectance for a beam of light normally incident on a surface separating two
materials of refractive indices n1 and n2 is given by ? ¿
n1 n2 2 n1 n2 2 reflectance increases
as the angle of incidence decreases from 90 degrees.;
