  1. visible light - What determines color -- wavelength or frequency ...

    What determines the color of light -- is it the wavelength of the light or the frequency? (i.e. If you put light through a medium other than air, in order to keep its color the same, which one wou...

  2. Why color depends on frequency and not on wavelength?

    Feb 24, 2024 · The wavelength is not. This means that, in situation where light is travelling through different media (air, water, lenses, corneas, fluid in the vitreous body in the eye), the …

  3. Wavelength of "complementary colours"? - Physics Stack Exchange

    Dec 3, 2023 · My question is, is there a way to mathematically define the "complementary wavelength" of some colour in the visible spectrum, or is the notion of complementary colours …

  4. Wavelength of black color - Physics Stack Exchange

    Mar 14, 2019 · Wavelength happens in the physical world. Color happens in your brain. "Black" is our name for how we perceive something that emits/reflects substantially less light than other …

  5. Can every color in the RGB space be generated with a single …

    Apr 20, 2018 · Could each of these colors also be generated by a single wave? As an example, consider the visible light spectrum illustrated in the following figure. Adding a wave with a …

  6. What do the $x$ and $y$ axes mean on a chromaticity diagram?

    Apr 26, 2024 · I understand that the chromaticity diagram is a plot of visible wavelength colors. Since the visible wavelengths form a curve on the graph, what do the $x$ and $y$ axes mean?

  7. Do colors differ in terms of speed? - Physics Stack Exchange

    Dec 9, 2019 · The speed of light is always c in vacuum, when measured locally, independent of the wavelength. Though, in a medium, the index of refraction is n=c/v. Speed of different em …

  8. How does light beyond the visible spectrum relate to color theory?

    Jul 10, 2024 · To get these values, a number of people were shown two colors: one monochromatic (single wavelength) color, and one mix of colors given by 3 predetermined …

  9. Physics of color: why do visible colors absorb all colors except the ...

    Aug 23, 2015 · Most objects of colors don't absorb all the energy of other wavelengths; they just absorb less of certain wavelengths, and we assign a color name based on the modified …

  10. optics - Why is wavelength of violet colour less than wavelength of ...

    Jun 2, 2020 · The wavelength of light of specific colour increases as we go from left to right in the visible colour spectrum: "VIBGYOR". Wavelength of green lies between wavelengths of blue …
