E.1.10 (HL)—Bohr hydrogen levels question 1
[Maximum number: 1]
This question is in two parts.
The energies of the principal energy levels in atomic hydrogen measured in eV are given by the expression
En=−n213.6 where n=1,2,3
The visible lines in the spectrum correspond to electron transitions that end at n=2.
Calculate the energy of the level corresponding to n=2.
3.40 eV ;
