5. the lowest-frequency domain that we've needed to name. It extends from wavelengths of a kilometer or so, the longest that will propagate through the interstellar medium, down to about a millimeter (where we generally start speaking of the millimeter, microwave, or even far-infrared). Detection of radio radiation is often done using wave techniques rather than photon-counting, because of the low photon energies, and this offers distinct advantages for such applications as interferometery which astronomers working in the infrared and optical regimes view with some envy. From active nuclei, we often detect synchrotron radiation in this range - radiation produced as energetic charged particles (mostly electrons) produce when they are deflected by magnetic fields.
