SUMMARY

The discussion centers on the specific frequencies of Infrared (IR) and Ultraviolet (UV) light within the electromagnetic spectrum, explicitly excluding crossover areas with microwaves and X-rays. The defined frequency ranges are UV = <5.01e16 Hz and >8.01e14 Hz, and IR = <4.01e14 Hz and >5.01e12 Hz. Participants explore whether identifiable patterns, akin to visible colors, exist in the UV and IR regions, questioning if the same intervals that define visible colors apply to these invisible frequencies.

PREREQUISITES
  • Understanding of electromagnetic spectrum fundamentals
  • Knowledge of frequency and wavelength relationships
  • Familiarity with the Lyman and Paschen series in atomic physics
  • Basic concepts of color perception versus sensation
NEXT STEPS
  • Research the Lyman series and its implications in UV spectroscopy
  • Study the Paschen series and its relevance to IR spectroscopy
  • Explore the concept of color perception in relation to electromagnetic frequencies
  • Investigate the differences between visible light and other electromagnetic frequencies
USEFUL FOR

Physicists, optical engineers, and anyone interested in the properties of electromagnetic radiation and its applications in spectroscopy.

I am wondering if Science has determined specific frequencies for the two in-visible light areas ?

For the sake of brevity, only include the "pure" part of the band. For UV, do not include the crossover x-ray area, and for IR, do not include the crossover with the microwave band.

Assume that I know the general quantity already.
(UV = <5.01e16 , >8.01e14)
(IR = <4.01e14 , >5.01e12)

Another way of stating question: Do we see the same pattern of identifiable points (ie colors) in the UV and IR portion of the spectrum? These in-visible "colors" would be at the same intervals as the visible colors.

The only difference between visible light and rest of the EM spectrum is that our eyes are only sensitive to visible light.

It wouldn't be a very good idea to call bands of IR "IR colors," though, because color is a perception, not a sensation. In other words, if you percieve the color yellow, it may be the result of two distinct sensations:

1) Monochromatic yellow light
2) A mixture of monochromatic red and monochromatic green light

The two situations produce the exact same perception, but are actually very different.

chroot,

I appreciate your response, but I don't think we're on the same page.

I said "These in-visible "colors" would be at the same intervals as the visible colors."

By "in-visible", I'm saying "not seen",
and by putting quotations around "color", I'm saying "not really" color.

I'm looking for how far Lyman series predictions into UV will the same pattern go? (and Paschen series into IR)

The pattern is the same increments apart (between values of wavelength or frequency) that we define as separate colors.

I could also define the pattern as the total spread in value (w or f) of visible light. Is this overall measurement repeated in the IR and UV portions of the EM spectrum?
