Beer-Lambert law given Intensity of Radiation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Absorbance = log10(Intensity of Incident Radiation/Intensity of Transmitted Radiation)
A = log10(I_i/I_radiation)
This formula uses 1 Functions, 3 Variables

Functions Used

log10 - The common logarithm, also known as the base-10 logarithm or the decimal logarithm, is a mathematical function that is the inverse of the exponential function., log10(Number)

Variables Used

Absorbance - Absorbance is also known as optical density of the solution used in calculating the concentration of a solution on the basis of its light absorption.
Intensity of Incident Radiation - (Measured in Watt per Square Meter Steradian) - The Intensity of Incident Radiation is the radiation intensity of incident radiation on a surface.
Intensity of Transmitted Radiation - (Measured in Watt per Square Meter Steradian) - The Intensity of Transmitted Radiation is the radiant flux emitted, reflected, transmitted, or received by a surface, per unit solid angle per unit projected area.

STEP 1: Convert Input(s) to Base Unit

Intensity of Incident Radiation: 200 Watt per Square Meter Steradian --> 200 Watt per Square Meter Steradian No Conversion Required
Intensity of Transmitted Radiation: 75 Watt per Square Meter Steradian --> 75 Watt per Square Meter Steradian No Conversion Required

What is Beer- Lambert Law?

Beer-Lambert law is useful in calculating the concentration of a solution on the basis of its light absorption. This law relates the intensity of the transmitted monochromatic light to the concentration of the solution and the thickness of the cell in which the solution is kept.
The molar extinction coefficient of a substance can be determined using a colorimeter or a spectrophotometer as follows. The absorbances of a solution are measured at different
known concentrations using a cell of known thickness (l). The plot of absorbance, A against Concentration of solution, c gives a straight line and its slope is equal to εl.

Define Photochemistry.

In photochemistry, we study the absorption and emission of light by matter. It consists of the study of various photo physical processes and photochemical reactions. Two important photo physical processes are fluorescence and phosphorescence. During fluorescence, light emission takes place in the presence of exciting radiation; but the light emission stops, once the exciting radiation is removed. In contrast to this, during phosphorescence, light emission takes place even after the removal of the exciting radiation.
In photochemical reactions, the substances acquire the necessary activation energy through light absorption. Again this is in contrast to the thermal reactions in which the reactants acquire their activation energy through collisions between molecules.
