Beers Law The amount of radiation absorbed may be measured in a number of ways Transmittance: T=P/Po. Transmittance %T=100T Absorbance: A=lg Po/P a=lg1/t A=lg100/%T A=2-Ig%T %o Transmittance 201.5100B070605 Absorbance
P The amount of radiation absorbed may be measured in a number of ways: Transmittance: T = P / P0 , % Transmittance, %T = 100 T Absorbance: A = lg P0 / P A = lg 1 / T A = lg100 / %T A = 2 - lg%T
