Hace 3 días · Ultraviolet ( UV) light is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun.
Hace 1 día · The Sun is the star at the center of the Solar System. It is a massive, nearly perfect sphere of hot plasma, [18] [19] heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.
Hace 5 días · The entire electromagnetic spectrum, from the lowest to the highest frequency (longest to shortest wavelength), includes all radio waves (e.g., commercial radio and television, microwaves, radar ), infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
Hace 5 días · El índice ultravioleta (UV) es una medida internacional de la intensidad de la radiación UV del sol en un lugar y momento específicos. Este índice ayuda a las...
Hace 2 días · In fact, stellar electromagnetic radiation spans the entire electromagnetic spectrum, from the longest wavelengths of radio waves through infrared, visible light, ultraviolet, to the shortest of X-rays, and gamma rays.
Hace 2 días · What is Venus made of? Venus photographed in ultraviolet light by the Pioneer Venus Orbiter (Pioneer 12) spacecraft, February 26, 1979. Although Venus's cloud cover is nearly featureless in visible light, ultraviolet imaging reveals distinctive structure and pattern, including global-scale V-shaped bands that open toward the west (left).
Hace 4 días · Ultraviolet (UV) radiation from the sun poses significant risks to eye health. It can potentially lead to various conditions, such as cataracts, macular degeneration, and even eye cancer. One way to safeguard your eyes from these harmful effects is by wearing sunglasses with proper UV protection.
