The energy of the emitted light (2.3393 eV) can be used to determine the color of light absorbed by the dye, as the absorbed color is complementary to the emitted color. In this case, the dye emits light corresponding to a certain color, and the task is to identify the color it absorbs, which is red, as it is the complementary color to the emitted light."}
