Problem
A collection of hydrogen atoms is prepared with each electron in the fifth orbit (n=5). Only those radiations that end on the second orbit (Balmer series) are allowed to pass through a spectroscope.
(i) Determine the number of distinct Balmer lines that can appear from this collection.
(ii) Arrange these Balmer lines in order of increasing frequency.
(iii) Calculate the wavelength of the shortest Balmer line that can be observed in this experiment. Use RH=1.097×107m−1.
