Original Note:
Rainbows occur as sunlight scatters off raindrops, slowing and changing direction via air-to-water refraction. This separates the different wavelengths of light within sunlight into its constituent colours, with shorter blue/violet bending more than longer red wavelengths. https://www.metoffice.gov.uk/weather/learn-about/weather/optical-effects/rainbows/how-are-rainbows-formed
