Daylight is the combination of all direct and indirect sunlight during the daytime. This includes direct sunlight, diffuse sky radiation, and (often) both of these reflected by Earth and terrestrial objects, like landforms and buildings. Sunlight scattered or reflected by astronomical objects is generally not considered daylight.

Web7. sep 2024 · Metallic Reflection. When a light beam encounters a material, radiation can be absorbed or reflected by the surface. Metals are known for having high reflectivity, which explains their shiny appearance. Since the reflectance of light by metals is high their absorption is low because the sum of both must correspond to 100% of the incident light. http://ser.sese.asu.edu/SPECTRA/intro.html

WebSunlight is composed of visible, infrared, and ultraviolet light. Ultraviolet and infrared light are portions of the electromagnetic spectrum that are invisible, yet harmful, to the human eye.
