That's a good follow-up. If rainbows have non-visible wavelength components (as it appears they do, from experimentation), where would those spacially appear on the rainbow? The assumption would be "on either side", but I suppose there's also the possibility that you start to get repetition at the same angle from viewer, so you'd have multiple bands overlapping?
