Pneumonic for the Electromagnetic Wave Spectrum

If you're like me and find it easier to remember things with a pneumonic, like remembering the order of planets from the Sun (e.g. "My Very Efficient Mind Just Sucked Up Nine Planets" for Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto), then this clever little pneumonic with I coined on a bus journey to school prior to my Physics exam I had later that day, might just help you.

Of course, it can sometimes be more useful to create your own, as this can increase the length of time you remember it for!
