excited electron उदाहरण वाक्य

उदाहरण वाक्य

1. At high frequencies ( such as UV and above ), molecules cannot relax, and the energy is purely absorbed by atoms, exciting electron energy levels.
2. Excitations are created through the Coulomb interaction Uc between the core hole ( and in some cases the excited electron ) and the valence electrons.
3. Instead, the still-excited electrons are transferred to a photosystem I complex, which boosts their energy level to a higher level using a second solar photon.
4. These excitons transfer energy to the electrons in the F-Centers with remarkably high efficiency, and these excited electrons are excited from the crystals in exciton-induced photoemission.
5. As these phonons strike other layers in the lattice, they excite electrons, which produce further phonons, which go on to excite more electrons, and so on.
6. When the incoming radiations are removed, the excited electron goes back to its original level, typically within a duration of around 10  " 8 seconds.
7. Spectral lines in atomic emission spectra, in particular, are the result of excited electrons falling from a higher energy state to a lower one, producing a photon.
8. The photovoltaic effect refers to photons of light exciting electrons into a higher state of energy, allowing them to act as charge carriers for an electric current.
9. For an atom in a multiple Rydberg state, the additional term, " U ee ", includes a summation of each " pair " of highly excited electrons:
10. Direct relaxation of the excited triplet to the ground state, termed phosphorescence, requires both emission of a photon and inversion of the spin of the excited electron.
