Quantum physics (photons)

  1. Mar 29, 2010 #1
    According to Einstien's theory, energy of one photon is absorbed by one electron. Is this photon is smaller than electron? If not, why energy of photon is not absorbed by other subatomic particles.

    This is incorrect.

    Presuming that you are referring to the photoelectric effect, the energy of a photon is absorbed by the WHOLE SOLID, resulting in the excitation of a conduction electron to a higher state. It is the whole solid that participates in this process (it requires the whole solid to create conduction electrons in the first place!).
