Answer:
So, if all the light passes through a solution without any absorption, then absorbance is zero, and percent transmittance is 100%. If all the light is absorbed, then percent transmittance is zero, and absorption is infinite.
Absorbance is the inverse of transmittance so,
A = 1/T
Beer's law (sometimes called the Beer-Lambert law) states that the absorbance is proportional to the path length, b, through the sample and the concentration of the absorbing species, c:
A ∝ b · c
As Transmittance, [tex]T =\dfrac{P}{P_0}[/tex]
% Transmittance, [tex]\%T=100\times T[/tex]
Absorbance,
[tex]A=\log_{10} \dfrac{P_0}{P}\\\\A =\log_{10}\times \dfrac{1}{T}\\\\A=\dfrac{\log_{10} 100}{\%T}\\\\A=(2 - log_{10})\times \%T[/tex]
Hence, [tex]A=\log_{10}\times \dfrac{1}{T}[/tex] is the algebraic relation between absorbance and transmittance.
