Can visible light or infrared radiation excite electrons?

Web22 de mar. de 2024 · Flames can be utilized to excite atoms as well. During a flame test experiment, metal chlorides are directly placed into a flame. The intense heat will promote the metal's electrons to an excited state. Upon emission, this extra energy is released in the form of visible light. Web21 de ene. de 2010 · Since the Fermi momentum (energy) is measured at absolute zero. At absolute zero the fermi momentum is the highest momentum an electron can have in the system. Most electrons sit below this energy. As you increase the temperature you are able to thermally excite electrons close to the fermi surface to energies above P f and E f.
