The Beer-Lambert Law

The Beer-Lambert Law describes how light intensity decreases as it passes through a transparent material containing a substance. It states that the amount of light absorbed depends on the concentration of the substance and the length of the path the light travels. Essentially, a higher concentration or thicker sample results in less transmitted light. This relationship helps scientists measure the concentration of a substance in a solution by observing how much light it absorbs, providing a precise way to analyze chemical materials electronically and efficiently.
