Given below is some famous number associated with electromagnetic radiations in different contexts in physics. State the part of the electromagnetic spectrum to which belongs. 1057 MHz (frequency of radiation arising from two close energy levels in hydrogen, known as Lamb shift).

A hydrogen like species (atomic number Z) is present in a higher excited state of quantum number n. This excited atom can make a transitionn to the first excited state by successive emission of two photons of energies 10.20 eV and 17.0 eV respectively. Altetnatively, the atom from the same excited state can make a transition to the second excited state by successive of two photons of energy 4.25 eV and 5.95 eVv respectively. Determine the value of Z.
