7 octaves above cover the UV spectrum and 7 octaves below cover the IR spectrum. I guess our eyes could see 14 octaves with 50 instead of 3 sensors per pixel.

A more practical solution is a separate device, I mean organ, that works like our ear but for em waves: just one "pixel" but with lots of sensors and complex postprocessing to detect harmonics. This way we could hear em waves.
Such a device can be built, actually.
- jacquesm 5y agoNot octaves. An octave is a doubling of frequency. When you go seven octaves below 'red' you are much, much lower than IR and when you go 7 octaves above blue you are way higher than UV.
- akomtu 5y agoAm I? 7 octaves above 400nm is 3-4nm, somewhere between extreme UV and x-ray. 7 octaves below 700nm is about 0.7mm - the end of IR and beginning of microwave spectrum. Unless I'm really missing something in my calculations.
