When an electron in an atom falls from higher orbit to a lower orbit a photon gets emitted. Since the electrostatic potential-energy of the electron is negative, because of the attractive force between the proton and the electron, the fall of electron makes its potential-energy more negative....

If the sample can transfer its energy to a neighbor while it is in the excited state, then the emitted light becomes further depolarized. Each transfer results in more depolarization. We have developed theoretical methods to determine the number of subunits in an energy transfer complex from the...
EXPLANATION: Thus the kinetic energy of the emitted photoelectrons depends on wavelength, frequency of the incident photon, and work function of the metal butdoes not depend onthe intensity. Where is the maximum kinetic energy in a pendulum? An active pendulum has the most kinetic energy atthe ...
Tags Energy Frequency Photon Wavelength In summary, the conversation discusses a problem involving the capture of a free electron by a stationary proton to form an excited state of the hydrogen atom. During this process, a photon of energy Ea is emitted, followed by another photon of energy 10....
The fluorophores were excited with a blue light at 4880A˚ and then they re-emitted a broadband fluorescence radiation peaked at 5190A˚, thus the difference between the absorbed and re-emitted photon energies resulted in a concentration of an average energy of 0.19 eV at the fluorophores ...
The energy of the emitted photon is not exactly known. It's somewhere near the energy difference between the energy states in the transition, but the idea of an "energy state" is some kind of approximation, using the time-independent Schroedinger equation when the real problem is time-...

Photons of the band-gap energy are emitted when electrons descend from the bottom of the conduction band to recombine with holes at the top of the valence band. The transition between the two involved states must conserve electron momentum. Similarly, when a photon whose energy is equal to or...
Another important mechanism of the energy absorption is the thermal self-action of light due to heat diffusion which can be described by the coupling between the NLS equation and the heat diffusion equation (e.g., Litvak et al., 1975; Bertolotti et al., 1997, and references therein). Th...
