WebAug 26, 2024 · An object gets its color when electrons absorb energy from the light and become “excited” (raised to a state of increased energy). The excited electrons absorb certain wavelengths of light. What humans see is the complementary color of the absorbed wavelengths, i.e., the remaining wavelengths of light that are not absorbed. WebLight that is absorbed by an object is usually converted into heat energy. The goal of this project is to measure how much heat is produced by the absorption of light by different colors.
