I would disagree with this characterization of light and brain waves. The various portions of the em spectrum are distinct in terms of their optical properties.

The various portions of the em spectrum are distinct in terms of their optical properties. To some extent this is related to the common types/state of matter on earth but in other ways it is related to the sizes of atoms, molecules and the such and this has some basis in fundamental constants.
Similarly alpha and theta rhythms have clear physiological relationships. There is some debate about whether gamma is a true oscillation but gamma activation is clearly indicative of neural/cognitive activity in a way that theta and alpha are not.

And the frequency of a brain wave makes it useful for thinking about tasks of different temporal sizes. I think that thinking of these waves as the same phenomena with the same rules but on different scales is a more powerful tool than trying to divide a continuous spectrum into a large taxonomy with "known" properties. If we thought of the radio spectrum as communication waves, infrared light as waves to do with heat, and visible light as a medium only for localized spatial information, then we would be stumped by the cosmic microwave background, TV remotes , and light houses.
