Reflectance - Wikipedia
网页Appearance. Spectral reflectance curves for aluminium (Al), silver (Ag), and gold (Au) metal mirrors at normal incidence. The reflectance of the surface of a material is its effectiveness in reflecting radiant energy. It is the fraction of incident electromagnetic power that is reflected at the boundary.
反射率（Reflectance）与反照率（Albedo） - CSDN博客
网页2019年6月14日 · 反射率（reflectance)是指某一波段向一定方向的反射，因而反照率是反射率在所有方向上的积分；反射率是波长的函数，不同波长反射率不一样，反照率是对全波长而言的。

反射率 - 维基百科，自由的百科全书
网页反射率（英語： Reflectivity 或 Reflectance ）是在一个界面反射中，反射波與入射波功率的比值。 注意，它不等同于 反射系数 （英語： Reflection coefficient ），反射系数定义为电磁波反射波与入射波的振幅比 [ 1 ] 。
Reflectance, Reflectivity, and the Solar Reflectance Index
网页2020年4月6日 · Reflectance Definition: Reflectance is defined as the ratio of the radiant flux reflected from a surface to the incident radiant flux, and it is unitless. Types of Reflectance: There are two types of reflectance: specular (mirror …
Reflectance Definition & Meaning - Merriam-Webster
网页The meaning of REFLECTANCE is the fraction of the total radiant flux incident upon a surface that is reflected and that varies according to the wavelength distribution of the incident radiation; broadly, nontechnically : reflectivity. How to use reflectance in …
Reflectance - an overview | ScienceDirect Topics
网页The reflectance is the proportion of directly incident light, conventionally expressed as a percentage, that is reflected from a plane polished surface, usually under oil-immersion, and under specified conditions of illumination. The reflectance of coal is rather low and is usually dominated by the vitrinite reflectance.
Reflectance - an overview | ScienceDirect Topics
网页Reflectance is the ratio of energy reflected to the total energy incident on a body, expressed in percentage. An object appears green because it reflects only wavelengths corresponding to green color in the visible spectrum.
Reflectance – reflectivity, diffuse scattering, hemispherical ...
网页The term reflectance is defined as the ratio of reflected radiant flux (optical power) to the incident flux at a reflecting object – for example, an optical component or system. It generally depends on the direction of incident light and on the optical frequency or …
Light - Reflection, Refraction, Physics | Britannica
网页2024年8月21日 · Light - Reflection, Refraction, Physics: Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle ...
