Yesterday afternoon I saw the beautiful Rainbow around the sky near my house, but I forgot to photograph it. The rainbow is a symptom of optics and meteorology in the form of light of varying color parallel to each other. Rainbow is a color spectrum arc that occurs due to the refraction of sunlight by the grains of water. Sunlight consists of many colors. The white color of the sun's light is a combination of different lights with different wavelengths. Then, the wavelength of the light forms a band of parallel lines called the color spectrum. This spectrum will be deciphered by water grains which then becomes Rainbow. This beautiful rainbow usually comes after the cessation of rain.
