Law of photometry
Web31 mrt. 2024 · Lambert’s law states that amount of transmitted light decreases exponentially with increase in thickness of absorbing medium. The two laws can be combined, hence I= {I_0}^ {\varepsilon cl} where I = Intensity of transmitted light I 0 = Intensity of incident light ε = Molar absorption coefficient c = Concentration of absorbing substance (g/dl) Web25 feb. 2024 · The working principle of the colorimeter is based on Beer-Lambert’s law which states that the amount of light absorbed by a color solution is directly proportional to the concentration of the solution and the length of a light path through the solution. A ∝ cl. Where, A = Absorbance / Optical density of solution. c = Concentration of solution.

WebColorimeter is based on two fundamental laws of photometry. We have discussed them below: Beer’s law: According to this law the amount of light absorbed is proportional to the solute concentration present in solution. Log10 I o /I t = a s c. where, a s is absorbency index. c is the concentration of solution. Lambert’s law:

Photometry attempts to account for this by weighting the measured power at each wavelength with a factor that represents how sensitive the eye is at that wavelength. The standardized model of the eye's response to light as a function of wavelength is given by the luminosity function.
