Sky gazers in India and in different components of the world will be capable of witness a blood moon on September 7 throughout a whole lunar eclipse. The moon will tackle a darkish red-copper hue. This is the results of a bodily impact called Rayleigh scattering.
During a whole lunar eclipse, the earth comes between the solar and the moon, blocking direct daylight from placing the lunar floor. However, not all daylight is blocked. Only the bluer mild is filtered out; the redder mild is scattered by the earth’s ambiance, giving the moon its placing color.
This phenomenon is called Rayleigh scattering. The British Nobel laureate John William Strutt (Lord Rayleigh) defined the phenomenon within the nineteenth century. When mild interacts with particles smaller than its wavelength, the depth of the scattered mild is inversely proportional to its wavelength. This is why earthsky seems blue: it has the shortest wavelength in seen mild.
During a blood moon, nevertheless, the bluer mild is absorbed by the earth’s ambiance whereas the redder mild is refracted in the direction of the moon. The exact hue depends upon mud and smoke ranges within the ambiance.
