Electromagnetic Spectrum

You’re going to need to know your way around the E-M spectrum.

For instance…

  • which type of radiation has the highest frequency?
  • what is range of wavelengths of visible light?
  • what types of E-M radiation can penetrate the atmosphere?

There are lots of diagrams showing the E-M spectrum. This is a pretty good one which gives some visual clues to help you remember the details.
