WebThis is called the measurement problem. the two slit experiment is a good test of the role of the observer in the quantum realm. any experimental design that attempts to determine which slit a photon has passed through (test for its particle nature) destroys the interference pattern (its wavelike nature) this is a breakdown of objective reality. WebThe energy of an electron present in ground state of a hydrogen atom will be, E = − 13.6 eV After absorbing 10.2 eV, the energy of the electron becomes E = − 13.6 + 10.2 = − 3.4 eV E = − 3.4 eV corresponds to the energy of the first excited state (n = 2) Thus, an electron jumps from ground state (n 1 = 1) to first excited state (n 2 = 2) WebMar 6, 2016 · The loss of energy of the incoming photon occurs when it ejects an outer-shell electron from a tissue atom. The ejected electron is called a Compton electron or secondary electron.
