Not all coloured patches are rainbows!

There are various shapes of the rainbow. There are several bows, a cross of a bow, a red bow, a double bow, a colored stripe, a dark band, a spoke, and so on. Photos and descriptions of the rainbow are here

The rainbow color pattern is different from the spectrum, and the color saturation is lower. For certain wavelengths, the rainbow has spectral blur because there is a distribution of exit angles rather than a single invariant angle. Furthermore, because the diameter of the sun disk (0.5 °) is not negligible compared to the rainbow width (2 °), the rainbow is a blurred version of the bow obtained from the point light source. Therefore, especially when droplets are particularly large or small, the number of bands in the rainbow may be different from the number of bands in the spectrum. Therefore, the color number of the rainbow is variable. However, if the word "rainbow" does not accurately represent the spectrum, it is the number of major colors in the spectrum.

The rainbow is scattered in the color range and is transmitted to the observer's eyes by water droplets. The "bow" part of the word explains the fact that rainbows are a group of nearly circular colored arcs with a common center. The sun always falls behind the people behind the rainbow. It makes the center of the rainbow face the opposite direction of the sun. Did you wonder why you see the color you made or watch the same color as other animals you see? Light bounces off from surrounding objects. When light enters our eyes, special cells tell us about the light of the brain. These cells are called photoreceptors. Light consists of small points called photons. When the sun shines, trillions of earth of these small rays will fall on the earth. Photons are reflected from almost everything, some of which come into our eyes. Let us see what comes into our eyes
