How much of the sun's radiation is reflected
WebThe Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the … WebUV radiation incident from an angle of 135°–150° behind a lens wearer is reflected from the back side of lenses. The usual antireflective coatings considerably increase reflection of UV radiation. To provide reliable labeling of the protective potential of lenses, an eye-sun protection factor (E-SPF®) has been developed.

WebIn total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface. The Earth radiates energy at wavelengths much longer than the Sun because it is colder. WebA 100% albedo (highest albedo possible) would be all the solar radiation being reflected away. A 0% albedo would mean none of the solar radiation is reflection and thus all is absorbed into or transmitted through the substance. First we will examine sun angle.
