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.
How to Calculate Thickness of Cell given Intensities of Radiation?
Thickness of Cell given Intensities of Radiation calculator uses Thickness of Cell = log10(Intensity of Incident Radiation/Intensity of Transmitted Radiation)*(1/(Molar Extinction Coefficient*Concentration of Solution)) to calculate the Thickness of Cell, The Thickness of cell given intensities of radiation formula is useful in calculating the concentration of a solution on the basis of its light absorption. Thickness of Cell is denoted by l symbol.
How to calculate Thickness of Cell given Intensities of Radiation using this online calculator? To use this online calculator for Thickness of Cell given Intensities of Radiation, enter Intensity of Incident Radiation (Ii), Intensity of Transmitted Radiation (Iradiation), Molar Extinction Coefficient (ε) & Concentration of Solution (c) and hit the calculate button. Here is how the Thickness of Cell given Intensities of Radiation calculation can be explained with given input values -> 2.3E+18 = log10(200/75)*(1/(0.0019*97)).
