Rainbow Cartoon Funny Animated






Rainbow Cartoon Funny Animated
A rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the Sun shines on to droplets of moisture in the Earth's atmosphere. It takes the form of a multicoloured arc. A rainbow spans a continuous spectrum of colours; the distinct bands (including the number of bands) are an artifact of human colour vision, and no banding of any type is seen in a black-and-white photo of a rainbow.

he light is first refracted entering the surface of the raindrop, reflected off the back of the drop, and again refracted as it leaves the drop. Contrary to popular belief, the light at the back of the raindrop does not undergo total internal reflection, and some light does emerge from the back. However, light coming out the back of the raindrop does not create a rainbow between the observer and the Sun because spectra emitted from the back of the raindrop do not have a maximum of intensity, as the other visible rainbows do.
