0408-ABED_1: Observe - Light and colour

You saw in the last activity how shining white light through a prism produced a rainbow of colours.

We call this rainbow a spectrum. White light contains all the colours of the spectrum mixed together: red, orange, yellow, green, blue, and violet. We can see the colours only when they are separated.

Raindrops can act as a prism and separate white light into the spectrum of colours. This is how a rainbow is produced. The light in the sky is refracted through the water in the raindrops.
