When to use it
Use it when ordering the EM spectrum by wavelength or frequency, with radio at the long-wavelength end and gamma at the short-wavelength end.
Example
Radio waves have wavelengths measured in meters; gamma rays have wavelengths smaller than an atom, placing them at opposite ends of the spectrum.
Common mistake
Placing visible light at the end of the spectrum. Visible light sits in the middle, between infrared and ultraviolet.
