A rainbow is formed due to the refraction (or bending) of light through raindrops (or a prism in Year 7 science labs) such that the white light is separated into a spectrum of colours. I teach my students to remember the correct order of the colours of a rainbow using a mnemonic: Richard Of York Gave Battle In Vain (red, orange, yellow, green, blue, indigo, violet). And that the blue end of the spectrum is more bent, putting it on the inside of the rainbow.
Science lessons aside; I love that the colours of the rainbow all come from the same source, and that the visibility of the rainbow depends on your position in relation to the sun. I find this is a wonderful metaphor for life and often use it to remind myself to find the silver lining in any situation.Click the button below to see other images of life.
