  1. What is the difference between reflectivity and reflectance?

    Aug 2, 2023 · What is the difference between reflectivity and reflectance? Ask Question Asked 2 years, 4 months ago Modified 2 years, 1 month ago

  2. Why do metals have high optical reflectivity? - Physics Stack Exchange

    Aug 26, 2018 · Why do metals have high optical reflectivity? Ask Question Asked 7 years, 4 months ago Modified 6 years, 7 months ago

  3. Why is there emissivity + reflectivity + transmittance = 1?

    Aug 29, 2017 · Reflectivity, Absorptivity, and Transmissivity are defined as being fractions of the original incident light. So you could have 30% reflected, 10% absorbed, and then you would know 60% was …

  4. Reflectivity with complex refraction indices - Physics Stack Exchange

    Mar 24, 2017 · Reflectivity with complex refraction indices Ask Question Asked 8 years, 9 months ago Modified 5 years, 3 months ago

  5. electromagnetic radiation - The rule breaker, emissivity + reflectivity ...

    Apr 3, 2013 · The emissivity and reflectivity only have to add up to one at the same wavelength. So if the emissivity is high for infra-red that doesn't clash with the reflectivity being high for visible light.

  6. optics - Do mirrors reflect all wavelengths of the electromagnetic ...

    Sep 2, 2016 · Some gammas are well in the low keV range, and x-ray mirrors would reflect them just fine. Further, this really doesn't address what factors drive the reflectivity of a material. For example, …

  7. Why does the polarization type ($s$ or $p$) of electromagnetic waves ...

    Aug 26, 2020 · So the Fresnel equations can describe the reflectivity and transmission of $s$ and $p$ polarized light and show that there is a different relationship between angle of incidence and the …

  8. everyday life - How reflective is the aluminum foil used for food ...

    Sep 25, 2020 · Household aluminum foil reflectivity measurements Science Direct article Pulling a diagram from that article: The reflectivity of household aluminum foil is quite good, but depending on …

  9. Does reflection depend on wavelength? - Physics Stack Exchange

    May 19, 2021 · The reflectivity of the cornea will for sure depend on wavelength and there are likely numerous studies on this topic because of high relevance for medical and eye-safety purposes.

  10. quantum mechanics - How do metals reflect electromagnetic radiation ...

    May 6, 2020 · Microwaves, for example, can be reflected off metallic surfaces. This seems counter-intuitive, since the metal's electrons could interact with the electric field component of the EM wave …
