  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, 3 months ago Modified 2 years ago

  2. 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 …

  3. Reflectivity with complex refraction indices - Physics Stack Exchange

    Mar 24, 2017 · Reflectivity with complex refraction indices Ask Question Asked 8 years, 8 months ago Modified 5 years, 1 month ago

  4. electromagnetic radiation - The rule breaker, emissivity

    Apr 3, 2013 · If emissivity and reflectivity are inversely proportionate, why does glass have a high emissivity of around 0.95-0.97 as well as being very reflective for IR Radiation? normally it …

  5. Why do metals have high optical reflectivity? - Physics Stack …

    Aug 26, 2018 · Why do metals have high optical reflectivity? Ask Question Asked 7 years, 2 months ago Modified 6 years, 6 months ago

  6. optics - Why does light reflect more intensely when it hits a …

    This influence suppresses the radiation in the polarization plane and perpendicular (90°) to the propagation direction fully, thus the reflection initially follows the s-polarization reflectivity but …

  7. 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 …

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

    Sep 2, 2016 · Similarly, if you look at metals like silver, you'll find great reflectivity across the visible spectrum and decent reflectivity across the IR range, but at high frequency ranges, the …

  9. UV reflective surfaces - Physics Stack Exchange

    In physics, the reflectivity of a surface is described by Fresnel Equations. One of the parameters of this equations is the refractive index which in general depends on the wavelength of light …

  10. does anodizing aluminum change its reflectivity at 532nm

    0 Does anodizing aluminum change its reflectivity at 532nm? I have tested percent reflection of highly polished aluminum at 532nm. I am concerned that the aluminum will oxidize and …
