An electron in a hydrogen atom makes a transition from the ground level to the third level. If the energy at the ground level; calculate the energy at the third level. [h = 6.6 x 10^-34Js; f = 10^15Hz]

A. 1.41eV
B. 1.71eV
C. 1.61eV
D. 1.51eV

Correct Answer:

Option D – 1.51eV

Explanation

E = Eo/n² = 13.6/3² = 13.6eV/9

= 1.51eV
