This article is about the Fresnel equations describing reflection and refraction of light at uniform planar interfaces. For the diffraction of light through an aperture, see Fresnel diffraction. For the thin lens and mirror technology, see Fresnel lens.
Partial transmission and reflection of a pulse travelling from a low to a high refractive index medium.
At near-grazing incidence, media interfaces appear mirror-like especially due to reflection of the s polarization, despite being poor reflectors at normal incidence. Polarized sunglasses block the s polarization, greatly reducing glare from horizontal surfaces.
The Fresnel equations (or Fresnel coefficients) describe the reflection and transmission of light (or electromagnetic radiation in general) when incident on an interface between different optical media. They were deduced by French engineer and physicist Augustin-Jean Fresnel (/freɪˈnɛl/) who was the first to understand that light is a transverse wave, when no one realized that the waves were electric and magnetic fields. For the first time, polarization could be understood quantitatively, as Fresnel's equations correctly predicted the differing behaviour of waves of the s and p polarizations incident upon a material interface.
