C. Table 3: Assigament of Observed Lines in the Hydrogen Spectrum Wavelength, Assignment Wavelength, Assignment Wavelength, Assignment 1121 97.26 102.57 121.57 389.02 397.12 - 1005.2 434.17 1094.1486.27 1282.2 1875.6 656.47 40452.3 954.86 The lines of the Balmer series lie between 250 nm and 700 nm. Based upon your assignments, what do all of the lines of the Balmer series have in common? What is the transition associated with the longest wavelength possible in the Balmer series? What is the transition associated with the shortest wavelength possible in the Balmer series?

Explanation / Answer

If you fill the table you will find that Balmer series have all the lines in visible region and all of them starts from n = 2 .

So for Balmer series it can be written as :

1/ = R{1/22 - 1/n2}

R = rydberg constant = 1.09737×107 m1

2.

for longest wavalength

1/ = 1.09737×107 m1 {1/4 - 1/32} the less is the right hand , more is wavelength ,which is least for( 1/22 - 1/32)

= 6.56 x 10-7 m = 656 nm

for shortest wavelength

1/ = 1.09737×107 m1 {1/4 - 0} n = infinity hence 1/n = 0

= 3.64 x 10-7 m = 364 nm
