The Beer-Lambert Law

The Beer-Lambert law describes the linear relationship between the absorbance of light and the concentration of an absorbing species. The relationship is defined by the formula: A = εlc, where:

• A is the absorbance (unitless).
• ε is the molar absorptivity or extinction coefficient.
• l is the path length of the light through the sample.
• c is the concentration of the absorbing species.

This law establishes a direct correlation between absorbance and concentration under specific conditions, such as using a dilute solution and monochromatic light. It is a fundamental principle used for quantitative analysis in methods like UV-Vis spectroscopy and infrared spectroscopy. In a linear calibration plot where the path length is 1 cm, absorbance...

The elasticity of demand refers to the degree of responsiveness of quantity demanded of a commodity to a change in its price or any other factor).
The concept of elasticity of demand is of great importance to producers, farmers, workers, and the Government. Lord Keynes considered this concept to be the most important contribution of Alfred Marshall.
The importance of elasticity of demand can be explained with the help of the following points:
1. Importance to a Producer: Every producer has to decide the price of his product at which he has to sell it. The concept of elasticity of demand becomes important for this purpose. If the producer is producing a commodity whose demand is relatively inelastic, then he can set a high price for it. Similarly,... Continue reading "Importance of Elasticity of Demand in Economics" »
