2. Primer (cosmetics) - Wikipedia

   en.wikipedia.org/wiki/Primer_(cosmetics)

   Some foundation primers are tinted to even out or improve skin tone or color. Others give a pearlized finish to make the complexion more light reflective. There are also foundation primers which are mineral-based primers, which contain mica and silica. Eyelid or eye shadow primers are similar, but made specifically for use near the eyes. An ...

4. Anti-reflective coating - Wikipedia

   en.wikipedia.org/wiki/Anti-reflective_coating

   For the simplified scenario of visible light travelling from air (n 0 ≈ 1.0) into common glass (n S ≈ 1.5), the value of R is 0.04, or 4%, on a single reflection. So at most 96% of the light (T = 1 − R = 0.96) actually enters the glass, and the rest is reflected from the surface. The amount of light reflected is known as the reflection loss.

5. Thin-film interference - Wikipedia

   en.wikipedia.org/wiki/Thin-film_interference

   Thin-film interference is a natural phenomenon in which light waves reflected by the upper and lower boundaries of a thin film interfere with one another, increasing reflection at some wavelengths and decreasing it at others. When white light is incident on a thin film, this effect produces colorful reflections.

6. Fresnel equations - Wikipedia

   en.wikipedia.org/wiki/Fresnel_equations

   Four weeks before he presented his completed theory of total internal reflection and the rhomb, Fresnel submitted a memoir [30] in which he introduced the needed terms linear polarization, circular polarization, and elliptical polarization, [31] and in which he explained optical rotation as a species of birefringence: linearly-polarized light ...

7. Oren–Nayar reflectance model - Wikipedia

   en.wikipedia.org/wiki/Oren–Nayar_reflectance_model

   This model for diffuse reflection was proposed by Johann Heinrich Lambert in 1760 and has been perhaps the most widely used reflectance model in computer vision and graphics. For a large number of real-world surfaces, such as concrete, plaster, sand, etc., however, the Lambertian model is an inadequate approximation of the diffuse component.
