Which of the following statements is incorrect with respect to Beer-Lambert law?
-- Io/I give transmittance
-- The amount of light absorbed is proportional to concentration of absorbing substance
-- Intensity of transmitted light decreases exponentially with increase in concentration of absorbing substance
-- Transmittance measures the amount of light transmitted after passing through the medium
Homework Answers
Answer :
Incorrect statement is - Io/I gives transmittance .
Actually transmittance = I / Io .
Io = intensity of incident light
I = intensity of transmitted light through sample
I/ Io = fraction of light transmitted through sample (measure of transmittance)
All other statements are correct .

The intensity of light transmitted through an absorbing solution is given by the Beer-Lambert law, 1 = lo exp (-€*cxd), where lo is the intensity of the light source, ε is the molar absorptivity of the absorber, c is the concentration of the absorber in the solution and d is the distance travelled by the light through the solution. Calculate the molar absorptivity of Rhodamine 6G dye given that only 20% of the light source's intensity is transmitted through 1...

Question 1 -- /1 The reaction described in the manual involves crystal violet which is purple colored in solution. Select the correct observations as the reaction proceeds. a As the reaction proceeds, the transmittance will decrease. As the reaction proceeds, the transmittance will increase. As the reaction proceeds, the purple color will become more pale. As the reaction proceeds, the purple color will become more intense. Absorption takes place here. The change in color of a solution can be measured...
