They are created when white light is refracted through a prism. This causes the light to split into the seven spectral colors visible to the human eye, i.e. into monochromatic light of a specific wavelength that cannot be further subdivided. If these spectral colors are combined again, white light is produced once more.<\/span><\/p>\n<p><span style=\"font-size: 120%;\">In nature, this phenomenon is best observed using the example of a rainbow. Sunlight is refracted by raindrops as if through a prism, causing the spectral colors to appear in the form of a rainbow in the sky.<\/span><\/p>\n<p><span style=\"font-size: 120%;\">The spectrum of light visible to humans lies between the long-wave end of ultraviolet light (360 to 380 nm) and the short-wave beginning of infrared light (780 to 820 nm). The perceived hue changes smoothly from violet to blue to green to yellow to red.<\/span><\/p>\n<p><span style=\"font-size: 120%;\">The seven spectral colors are violet, blue, green, yellow, orange, red and indigo. They can be assigned to the following wave ranges:<\/span><\/p>\n<ul>\n<li><span style=\"font-size: 120%;\">Violet: 380 to 430 nm<\/span><\/li>\n<li><span style=\"font-size: 120%;\">Blue: 430 to 490 nm<\/span><\/li>\n<li><span style=\"font-size: 120%;\">Green: 490 to 570 nm<\/span><\/li>\n<li><span style=\"font-size: 120%;\">Yellow: 570 to 600 nm<\/span><\/li>\n<li><span style=\"font-size: 120%;\">Orange: 600 to 640 nm<\/span><\/li>\n<li><span style=\"font-size: 120%;\">Red: 640 to 780 nm<\/span><\/li>\n<\/ul>\n<p><span style=\"font-size: 120%;\">The color indigo is located in a middle range between the blue and the green wavelength range.<\/span><\/p>\n\t<div id=\"gap-946290178\" class=\"gap-element clearfix\" style=\"display:block;
