What are some notable ranges of the electromagnetic spectrum?

The most familiar range is the visible spectrum – ranging from the short violet wavelengths to the the long red wavelengths. Most humans can see between 400nm and 700nm. Beyond the range of our vision exist shorter wavelengths of ultraviolet light, and longer wavelengths of infrared light. The higher the frequency of a photon, the more energy it has. World Star Tech carries laser diodes ranging from the ultraviolet 375nm to the infrared 1064nm.
