Can also just a part of a photon be absorbed by an electron?
Why is a photon completely absorbed by an electron and why is there no partial absorbtion?
How do we know if electrons actually go through the quantum processes of emitting and absorbing photons? When light is absorbed by a solid where does it go? What is the quantum mechanical explanation for why incident radiation undergoes absorption, transmission, and/or reflection? What is electron affinity in detail? Where does the energy that is released from an electron affinity come from? Why the electrons and nucleons are not visible? Does it related to wavelength of the light? And if Yes How? What is electron affinity? How does a photon lose energy? When light gets absorbed into a material, where does the light go? Why the atoms become neutral when it shares electron ? If light is said to have photon particles, then how come those particles can pass through solid glass but not through a wall? What is the half-life of a photon? How can a photon be created during photon-electron collision? When a light falls on an object, it absorbs some colours and reflects some. Where does the energy of the absorbed portion of the light go? How are electron, positron and gamma photon created from a vacuum? Why do electrons in an atom exist in discrete energy levels, and why don’t they fall into the nucleus or radiate electromagnetic energy as they orbit? Why does light posses a dual nature of both wave and particle only and nothing else? What is the definition of energy of a photon? How electron, positron and gamma photon created from vacuum? Why does light show the particle and wave both nature? How is the energy of a photon calculated? Why the electrons did not vanish from solar cell? In a double slit experiment, how do we know for sure that the electron duplicates itself when there is no way to distinguish between two electrons clearly? Why do not photons obey E = m c ^ 2? Is an electron beam deflected by strong light? Why do electrons and light show dual nature (both wave-like and particle-like properties)? Why atoms becomes neutral when it shares electrons? How different are photons compared to an atom? Do excited electrons release photons in a particular direction? Does it take any time for photons to be released or absorbed, or does it happen instantaneously?
