## Thickness of cell given intensities of radiation Solution

STEP 0: Pre-Calculation Summary
Formula Used
thickness_of_cell = log10(Intensity of incident radiation/Intensity of transmitted radiation)*(1/(Molar extinction coefficient*Concentration of solution))
l = log10(Ii/I)*(1/(ε*c))
This formula uses 2 Functions, 4 Variables
Functions Used
log10 - Common logarithm function (base 10), log10(Number)
log - Logarithm function, log(Number, Base)
Variables Used
Intensity of transmitted radiation - Intensity of transmitted radiation is the radiant flux emitted, reflected, transmitted or received by a surface, per unit solid angle per unit projected area. (Measured in Watt per Square Meter Spat)
Molar extinction coefficient - Molar extinction coefficient is a measure of how strongly a chemical species or substance absorbs light at a particular wavelength. (Measured in Square Centimeter per Mole)
Concentration of solution - Concentration of solution is the quantity of a solute that is contained in a particular quantity of solvent or solution. (Measured in Mole per Meter³)
STEP 1: Convert Input(s) to Base Unit
Intensity of incident radiation: 1 Watt per Square Meter Steradian --> 1 Watt per Square Meter Steradian No Conversion Required
Intensity of transmitted radiation: 10 Watt per Square Meter Spat --> 0.795800000000001 Watt per Square Meter Steradian (Check conversion here)
Molar extinction coefficient: 10 Square Centimeter per Mole --> 0.001 Square Meter per Mole (Check conversion here)
Concentration of solution: 100 Mole per Meter³ --> 100 Mole per Meter³ No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
l = log10(Ii/I)*(1/(ε*c)) --> log10(1/0.795800000000001)*(1/(0.001*100))
Evaluating ... ...

## 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.
