What is another word for coefficient of reflection?
Pronunciation: [kˌə͡ʊɪfˈɪʃənt ɒv ɹɪflˈɛkʃən] (IPA) 
The coefficient of reflection is a measure of how much light or energy is reflected off a surface. Synonyms for coefficient of reflection include reflection factor, reflectivity coefficient, and reflection coefficient. These terms are used interchangeably to describe the ratio of reflected light to incident light. Other related terms include Fresnel reflection coefficient, which refers to the reflection of light at the interface between two different refractive indices, and surface reflectance, which is the total amount of light reflected from a surface. Regardless of the specific term used, the coefficient of reflection is an important measure of the reflectivity of a surface, and is used in a wide range of applications, including optics, acoustics, and electromagnetic radiation.
