There are some good bits to this video but it instantly loses credibility when it gives a single frequency right down to a cycle to the 'color' cyan. The announcer then proceeds to discuss the wavelength (singular) of the 'color' purple when he should have said violet. When discussing purple the screen flashes up with a very reddy magenta which the video uses as an example.
This is all the more horrifying given that the principal part of his talk is about RF carriers and modulation systems on said carriers for cell phones.
I know things like this happen but one doesn't expect to see such a blatant example on HN.
I should have been more succinct here, as cyan is loosely described in the texts as a mixture of blue and green (two frequencies) or a color somewhere between green and blue. The author could have avoided confusion by selecting say 'green'.
However, there's no confusion about purple - in the video shown as magenta instead of violet as it is not on the spectrum of true colors (it being a mixture of blue and red):
