How does a rainbow occur?

Magic or physics? Many myths circulate about rainbows. A rainbow has though nothing to do with magic, but with physics. Reena explains, how a rainbow occurs and what spectral colours and light refraction have to do with it.

A rainbow occurs, when sunlight hits rain. Sunlight consists of so-called spectral colours, therefore the whole colour range. But our eye can normally only perceive a mixture of these colours. This mixture we perceive as white.

When light, however, hits upon a raindrop, it gets refracted. With refraction it is divided up into the colours of the spectrum. The colours red, orange, yellow, green, blue and violet can be best distinguished by the human eye.

The light not only gets refracted in the raindrop, but also reflected. The colours are therefore mirrored and consequently leave the raindrop in reverse sequence. A rainbow consists of a large number of raindrops, which refract and reflect the sunlight.
