The variability of the reflectance spectra for a number of subjects measured at NIST is determined using statistical methods. The degree of variability is explored and discussed.
Nist reflectivity

WebbOverview. When light strikes the interface between a medium with refractive index n 1 and a second medium with refractive index n 2, both reflection and refraction of the light may occur. The Fresnel equations give the ratio of the reflected wave's electric field to the incident wave's electric field, and the ratio of the transmitted wave's electric field to the … Webbyears, neutron reflectivity has emerged as a power- ful technique for the investigation of surface and in- terfacial phenomena in many different fields. Although similar studies on …
