Reflectivity of pvc

Web14. aug 2024 · 1 Absolutely. See Fresnel's equations. These show that reflection depends on angle of incidence, polarization, and refractive index. The simplest case (for reflection at normal incidence, where polarization doesn't matter) tells us that the reflectance is R = n 1 − n 2 n 1 + n 2 2 Web9. nov 2010 · Reflectance or Reflectivity Reflectance can be a complex phenomenon affected by molecules and sub-atomic particles both at and below the surface of a material. For most reasonably thick opaque materials, reflection occurs within the first few nanonmetres of the surface and any light transmitted more than about 100nm into the …
