   Different materials absorb photons of different wavelengths because absorption of a photon is an absorption of energy. Something must be done with that energy. In the case of ultraviolet and visible light, the energy is of the right general magnitude to excite an electron to a higher energy level.

   The electrons will absorb the energy of the light wave and change their energy state. There are several options that could happen next, either the electron returns to the ground state emitting the photon of light or the energy is retained by the matter and the light is absorbed.

   What is light absorption?

   • A Quick Overview of Light Absorption In absorption, the frequency of the incoming light wave is at or near the energy levels of the electrons in the matter. The electrons will absorb the energy of the light wave and change their energy state.

   What is the difference between adsorption and absorption?

   • The main difference between them is that adsorption is the adhesion of particles onto a substance, while absorption involves mass transfer into another material. But, adsorption and absorption involve other differences as well. Here is a comparison of adsorption and absorption, a closer look at their definitions, and examples of each process.

   What are examples of absorption?

   • Examples of absorption include: Uses of absorption include spill clean-up, hydration, and digestion. Note that there is another definition of absorption in science, referring to the interaction where matter absorbs energy from light.

   What happens if a molecule absorbs light?

   • They absorb the light. Generally, something in the molecule changes as a result. The molecule absorbs energy from the photon and is left in an excited state. The more of these molecules there are in the solution, the more photons will be absorbed. If there are twice as many molecules in the path of the light, twice as many photons will be absorbed.
