What is Lambert’s law related to?

Lambert’s law relates to illumination (option D). It describes how light is absorbed by a material, specifically focusing on how the intensity of illumination (light) decreases as it passes through or interacts with a material. The law states that the amount of light absorbed by a material is directly proportional to the thickness of the material and the concentration of the absorbing substance within it. This principle is fundamental in various fields, including optics, photography, and materials science, where understanding how light interacts with and penetrates materials is crucial. Lambert’s law helps quantify how much light is absorbed, reflected, or transmitted through different media, influencing everything from the design of optical instruments to the development of materials with specific light absorption characteristics. Unlike reflection (option A), refraction (option B), or interference (option C), Lambert’s law specifically addresses the interaction of light with materials in terms of absorption and illumination.
