Do emitted photoelectrons have same kinetic energy? Assertion : In the process of photoelectric emission , all theemitted photoelectrons have the same kinetic energy. Reason : The photon transfers its whole energy to the electron of the atom in photoelectric effect. What is the minimum kinetic en...
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....
How do I calculate the energy of a photon? To calculate the energy of a photon, follow these easy steps: If you know the wavelength, calculate the frequency with the following formula: f =c/ λ where c is the speed of light, f the frequency and λ the wavelength. If you know the ...

Within this picture, harmonic photons are emitted as a result of electrons following trajectories such that they recombine with their parent ion. We assume that an electron is photo-excited to the conduction band of the liquid at time tion. Following this, the Newtonian equations of motion can ...
Therefore, the power density, Pd, at a distance R from the transmitter antenna can be calculated using the following formula: Pd = Pt/(4πR2) Pt is the total power radiated by the antenna. This formula works for the power being emitted by an isotropic antenna. If the antenna is a dire...
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...
energy of the absorbed primary photon. The light pulses are collected by a photo-cathode. Electrons, emitted from thephotocathode, are accelerated by the applied high voltage and amplified at thedynodesof the attached photomultiplier (Figure 4). At the detector output an electric pulse proportional...
