WebThe fraction of radiation arriving at a surface that is reflected by it is called its reflectivity. Another property of the surface is its emissivity, which essentially is the surface’s tendency to emit radiation to other bodies. Surfaces with high emissivity are also very absorptive, that is, they Managed by With support from Web15. júl 2016 · Albedo refers to a material's ability to reflect sunlight. Examples are below. Explanation: Albedo is the measure of the reflectivity of a material. A high albedo means it reflects a lot of light and a low albedo means it absorbs a lot of light. An example of a high albedo material is snow and ice.

WebReflectivity It is the optical property of a material. When a light wave is incident on the polished surface of the material, the light returns back from the material surface and this is referred to as the reflection of light. Some of the materials show better reflectivity compared to other materials. White surface shows better reflection of light. For homogeneous and semi-infinite (see halfspace) materials, reflectivity is the same as reflectance. Reflectivity is the square of the magnitude of the Fresnel reflection coefficient, which is the ratio of the reflected to incident electric field; as such the reflection coefficient can be expressed as a complex number as determined by the Fresnel equations for a single layer, whereas the reflectance i…
