beer law

Beer's Law, also known as the Beer-Lambert Law, describes how the concentration of a substance in a solution affects its ability to absorb light at a specific wavelength. Essentially, it states that the more of the substance present, the more light it absorbs. This relationship is linear, meaning if you double the concentration, absorption doubles too. It’s widely used in chemistry and analytical testing to determine how much of a substance is in a sample by measuring how much light passes through it. The law helps in quantifying substances in liquids accurately.
