## Example Formula

The Fresnel reflectance of s-polarized light can be determined using the formula:

R = ((n1*cos(θ1) - n2*cos(θ2)) / (n1*cos(θ1) + n2*cos(θ2)))2

Where:

1. R: represents the Fresnel reflectance of s-polarized light.
2. n1: refers to the refractive index of the first medium.
3. n2: denotes the refractive index of the second medium.
4. θ1: represents the angle of incidence of the light wave.
5. θ2: signifies the angle of transmission of the light wave.

## Who wrote/refined the formula

The Fresnel equations, including the formula for Fresnel reflectance, were developed by Augustin-Jean Fresnel, a French physicist, in the early 19th century. Fresnel made significant contributions to the understanding of light and optics, particularly in the study of interference and diffraction phenomena. His work laid the foundation for the field of wave optics and has had a profound impact on our understanding of light propagation.

## Real Life Application

The concept of Fresnel reflectance of s-polarized light finds application in various fields, including optics, photonics, and telecommunications. One practical application is in anti-reflection coatings for optical components such as lenses and mirrors. By carefully designing the refractive index and thickness of these coatings, it is possible to minimize the reflection of light at the surface, improving the transmission of light through the component and reducing unwanted glare or reflections.
