radiated energy when an electron jumps from higher
energy level to lower energy level ?
(1) 2 x 10-14 sec-1 (2) 5 * 1014 sec-1
(3) 2* 1014 sec (4) 5 x 10-14 sec

Answer 1

Answer:

Given: 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

6.626×10

−34

⇒5.5×10
