Mirrors, rainbows and the blue sky, sentence 1

White sunlight is really a mixture of all the colours, and when it passes through a raindrop or a glass prism each colour bends by a slightly different amount, so they fan out into a rainbow.

Who acts: White sunlight, sunlight, colour, colours · What happens: be, pass, bend, fan out · To what, where: mixture, raindrop, rainbow

This is a sentence of the lesson «Mirrors, rainbows and the blue sky» of the physics course of Mova's primary school.
