The difference in energy between the two energy levels is 2.3eV.


To find: The frequency of radiation emitted when the atom makes a transition between the energy levels.


The energy between the energy levels is

E=2.3eV

⇒2.3×1.6×10

−19

J


The frequency of the radiations emitted during transition is:

E=hν

ν=

E

h

2.3×1.6×10

−19

6.626×10

−34

⇒5.5×10^ 14 Hz
