In the spectrum described below, lines are indicated that
were created as a result of photon emission due to
electronic transitions in a hydrogen-like atom (that is, an
atom in which there is only one electron). It is a given that
all the lines in the current spectrum were created due to
the return of an electron from some excited state to the
ground state. Given that the frequency of a photon
belonging to line C is 1.234x10^16 Hz . calculate the
energy of 4 moles of photons belonging to line A (an
answer must be given in kJ).
