　　Not long ago, a rare known as "fire Rainbow" natural phenomenon appeared in the United Kingdom over the West Yorkshire, is a semicircle, huge bright Rainbow, also accompanied by a stripe of blue, green, purple and orange light, and we'll see how it happened. Ted Baker Galaxy S4 Case

　　It is understood that the rainbows in our cognition is not the same phenomenon known as the Rainbow, but the stunning thing is neither fire, and nothing the least connection with the Rainbow. In addition, to all conditions of this natural phenomenon can be formed together, is not an easy task.

　　As reported in the foreign media ScienceAlert, want to see the fire in the sky a rainbow, requires the height of the sun above the horizon of 58 °, Sun also happened to pass on more than 6000 meters high Cirrus clouds made up of hexagonal ice crystals, these conditions are indispensable.

　　There are a series of requirements, because the Sun must be composed in such a precise angle to make fire Rainbow colors are visible. It is worth mentioning that, fire Rainbows usually appear sometime in the middle of a certain latitude of the area.

　　This natural phenomenon in the United States are relatively common, but for United Kingdom in Ambleside, and Cumbria and Norman town residents, fire-magic of the Rainbow is a rare beauty. If you want to see the natural beauty, it is best to go to somewhere near the equator, summer midday is the best time to discover fire Rainbow.

　　Amusing Plant coverage in the foreign media writes: "for example, in London, England, the Sun high 58 ° above the horizon the conditions of time between mid May to late July, total length about 140 hours. In the United States Los Angeles, from late March to late September this time, more than 670 hours that meet the criteria. "

　　An interesting question is whether fire Rainbow Rainbow? actually it was not Rainbows. Fire Rainbow formation with Sun and ice crystals in Cirrus clouds between the interaction mode. Common Rainbow is caused by light passing through the water droplets produced by refraction (or bent) form and reflected wavelengths of various colors, which is constituted of various colors of the Rainbow. Fire Rainbow formation is not the case, it is caused by the diffraction of light products.

　　Live Science says: "in process of diffraction of sunlight, light will be scattered into a circular pattern, as with other Flash objects, its color depends on the viewer's location, relative locations of diffraction in the Sun and of the viewers in different locations, and see a rainbow of colors may vary.
