A rainbow is perhaps the most beautiful optical phenomenon. It appears as a seven-coloured arc in the sky when there are raindrops in the air. It is visible when the sun is low in the sky (early mornings and late afternoons). To see the rainbow, you have to stand with the sun behind your back.
From where does a rainbow get its colours? The colours come from the dispersion of white light by raindrops suspended in the air. Sunlight entering a drop gets refracted and is split into its component colours. The lights of the component colours travel through the drop and fall on its It other side. A part of these lights get reflected, and a part goes out. (This is not total internal reflection.) The reflected lights again fall on the surface of the drop and get refracted on the way out. The two refractions bend the lights through a large angle, keeping them separate. The lights of different colours emerging from the raindrops create a rainbow, with creates a rainbow red at the top and violet at the bottom.
You can see the rainbow effect at fountains, water sprinklers, waterfalls, and so on. In all these cases, light is dispersed by the droplets of water in the spray. To see the effect, stand with the sun behind you when it is low in the sky.
