Also it’s interesting that NDT orients his EM spectrum by wavelength rather than frequency, such that “above red” and “below UV” falls outside the visible range. Is ascending wavelength the convention in astrophysics?
Not normally. In physics the general convention is to use photon energy. This puts Radio and IR 'below' red, and UV 'above'.
That makes sense. Might’ve just been an accidental swap. Tweets aren’t peer reviewed.
