Radio vs. Light
I seek a mnemonic for it because I sometimes teach the subject and I have to force the poor kids to memorize it. The order "radio waves, microwaves, infrared, visible, ultraviolet, x-rays, gamma rays" is a "required concept" in the New York State regents physics syllabus.

Cosmic rays are not part of the electromagnetic spectrum. That term is used to refer to high speed particles.
