Light reflectance equation
WebJan 30, 2024 · Figure \(\PageIndex{1}\): Light absorbed by sample in a cuvette. The intensity of the light passing through the sample cell is also measured for that wavelength - given the symbol, \(I\). If \(I\) is less than \(I_o\), then the sample has absorbed some of the light (neglecting reflection of light off the cuvette surface). WebThe law of reflection states that the angle of reflection equals the angle of incidence, or. The law of reflection is illustrated in Figure 1.5, which also shows how the angle of incidence …

Assuming this differential equation is the right one (or replacing it with another one which is right), then all you need to do is use a standard numerical partial differential equation solver. Matlab has them, so does Python, and many other languages. I wrote this answer just off the top of my head. Webthe reflectivity is. = %.

In the diagram on the right, an incident plane wave in the direction of the ray IO strikes the interface between two media of refractive indices n1 and n2 at point O. Part of the wave is reflected in the direction OR, and part refracted in the direction OT. The angles that the incident, reflected and refracted rays make to the normal of the interface are given as θi, θr and θt, respectively.
