Ask Question Asked 2 years, 8 months ago Modified 2 years, 5 months agoWed, 22 Apr 2026 05:00:00 GMThttps://physics.stackexchange.com/questions/835423/calculating-absorption-coefficient-from-transmittance-and-reflectanceI have some spectrum data from a sample, specifically the Transmittance and Reflectance of the sample. I would like to use this to calculate the absorption coefficient.Thu, 23 Apr 2026 23:00:00 GMThttps://physics.stackexchange.com/questions/485769/why-thickness-of-metal-thin-film-will-affect-reflectanceThe reflection of the interface of two layers is described by Fresnel's equations. For instance, the reflectance of an Al bulk at 1 micron is around 0.9, this is the reflectance of the interface be...Mon, 20 Apr 2026 12:19:00 GMThttps://physics.stackexchange.com/questions/467264/what-is-the-relation-between-reflectance-and-intensityAbsolute reflectance is difficult to measure. Intensity is considerably easier. Reflectance requires a calibrated detector system, or a known reference sample, or both. Even then, the measurement requires quite a bit of care. If the absolute reflectance is of little interest, there is little incentive to measure it.Sun, 12 Apr 2026 05:12:00 GMThttps://physics.stackexchange.com/questions/354322/why-is-there-emissivity-reflectivity-transmittance-1Foillowing this question, I understand that $emissivity + reflectivity + transmittance = 1$ Where does this relationship comes from? What are the physical phenomena ...Thu, 23 Apr 2026 07:01:00 GMThttps://physics.stackexchange.com/questions/465048/why-is-absorbance-calculated-as-log-101-r-and-not-1-rIn near-infrared spectroscopy, when measuring how light is reflected off of opaque samples, absorbance is commonly calculated using the same equation, but by simply substituting the transmittance for reflectance:Wed, 22 Apr 2026 12:24:00 GMThttps://physics.stackexchange.com/questions/787985/how-to-calculate-refractive-index-from-absorbance-transmittance-or-reflectance0 I have absorbance (Abs), reflectance (R%) and transmittance (T%) data of TiO2 deposited tin film on FTO glass substrate. The data was collected using UV-Vis spectrophotometer. How to calculate refractive index n from this? from the refractive index I will estimate the film thickness, then I will estimate the band gap of the thin film.Wed, 22 Apr 2026 06:19:00 GMThttps://physics.stackexchange.com/questions/351859/refractive-index-and-reflectionDoes the magnitude of the refractive index affect reflection? Will a ray be more reflected the higher the refractive index of the other medium is?Mon, 20 Apr 2026 10:25:00 GMThttps://physics.stackexchange.com/questions/138859/reflectance-and-wavelengthThe source mentions Matlab code that can do the calculations for you and you can buy commercial software that does this (and much more) based on either a description of the mirror's layers. That kind of software can usually also create a mirror from a required reflectance function.Sat, 18 Apr 2026 13:41:00 GMThttps://physics.stackexchange.com/questions/787880/how-to-calculate-refractive-index-n-from-absorbance-transmittance-or-reflecta?noredirect=1I have absorbance (Abs), reflectance (R%) and transmittance (T%) data of $\\rm TiO_2$ deposited tin film on FTO glass substrate.
