Problem
An electron in a hydrogen atom initially in the n=6 level makes a series of downward transitions until it reaches the ground state n=1.
(i) How many distinct photon wavelengths can be emitted in this entire process? Show the reasoning leading to your answer.
(ii) Calculate the shortest wavelength among all the emitted photons.
(iii) Calculate the longest wavelength that can be produced in these transitions.
Use h=6.63×10−34Js, c=3.00×108ms−1 and 1eV=1.60×10−19J. Express all wavelengths in nanometres.
