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 Slope?
Thickness of Cell given Slope calculator uses Thickness of Cell = Slope of Line/Molar Extinction Coefficient to calculate the Thickness of Cell, The Thickness of cell given slope formula is useful in calculating the molar extinction coefficient on the basis of its light absorption. Thickness of Cell is denoted by l symbol.
