Solution

Layman series for H - ion

$hc over straight lambda space equals space R h c space space open parentheses 1 over 1 squared minus 1 over 2 squared close parentheses and space for space straight H space minus space like space ion hc over straight lambda space equals space R h c space space open parentheses 1 over 2 squared minus 1 over 4 squared close parentheses therefore space space open parentheses 1 over 1 squared minus 1 over 2 squared close parentheses space equals space straight Z squared space space space open parentheses 1 fourth minus 1 over 16 close parentheses open parentheses 1 minus 1 fourth close parentheses space equals straight Z squared space space space open parentheses 1 fourth minus 1 over 16 close parentheses straight Z space equals space 2$
