PhysicsEasysingle choice

Two energy lavels of an electron in an atom are separated by 2.3 $e V$ . The frequency of radiation emitted when the electrons go from higher to lower level is

Options:

Answer:

Solution:

Given, $E_{2} - E_{1} = 2.3 e V$

Or v= $\frac{E 2 - E 1}{h} = \frac{2.3 \times 1.6 \times 10^{- 19}}{6.6 \times 10^{- 34}}$

= $0.55 \times 10^{15}$

= $5.5 \times 10^{14} H z$
