Q7 of 106 Page 384

A hydrogen atom emits ultraviolet radiation of wavelength 102.5 nm. What are the quantum numbers of the states involved in the transition?

As we consider ground state to be n=1, so the transition involved will be from n=1 to m = (TO BE DETERMINED).


As we know from the topic of hydrogen spectra,



Here, λ=102.5nm and Z=1(as atomic number of hydrogen is 1), n=1


Thus,
