Lambert-Beer Law

The Lambert-Beer Law describes how the intensity of light decreases as it passes through a transparent substance like a solution. It states that the decrease in light is proportional to the concentration of the substance and the distance it travels. Essentially, a higher concentration or a longer path results in less transmitted light. This principle allows scientists to determine the amount of a substance in a solution by measuring how much light it absorbs, making it valuable in fields like chemistry, biology, and medical testing.
