Answer to Question #188340 in Optics for lala

Question #188340

The difference between the transmittance coefficients of the same substance measured in the same cuvette at different wavelengths is equal to 100 (T1/T2 ). How many times are the optical densities changed (D1-D2=1 ) ?.

Expert's answer

"n=\\log_{10}(100(T_1\/T_2))=2+\\log_{10}\\frac {T_1}{T_2}."
