Metamaterials and Photonic Crystals
An absorption spectrum is a graphical representation that shows the wavelengths of light absorbed by a substance, revealing important information about its molecular structure and energy levels. When light passes through a material, specific wavelengths are absorbed by electrons transitioning to higher energy states, creating dark lines or bands in the spectrum, which correspond to these absorption events. The unique pattern of these lines serves as a fingerprint for identifying different substances.
congrats on reading the definition of absorption spectrum. now let's actually learn it.
