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 Intensity of Transmitted Radiation given Concentration of Solution?
Intensity of Transmitted Radiation given Concentration of Solution calculator uses Intensity of Transmitted Radiation = Intensity of Incident Radiation/exp(Molar Extinction Coefficient*Thickness of Cell*Concentration of Solution) to calculate the Intensity of Transmitted Radiation, The Intensity of transmitted radiation given concentration of solution formula is defined as the radiant flux emitted, reflected, transmitted or received by a surface, per unit solid angle per unit projected area. Intensity of Transmitted Radiation is denoted by Iradiation symbol.
How to calculate Intensity of Transmitted Radiation given Concentration of Solution using this online calculator? To use this online calculator for Intensity of Transmitted Radiation given Concentration of Solution, enter Intensity of Incident Radiation (Ii), Molar Extinction Coefficient (ε), Thickness of Cell (l) & Concentration of Solution (c) and hit the calculate button. Here is how the Intensity of Transmitted Radiation given Concentration of Solution calculation can be explained with given input values -> 200 = 200/exp(0.0019*5.05E-08*97).
