MCQ

The wavelength of a spectral line for an electronic transition is inversely related to :

A
the number of orbital undergoing the transition.
✓
the difference in energy levels involved in the transition.
C
the nuclear charge of an atom
D
the velocity of the electron undergoing the transition.

✓

Answer

Correct option: B.

the difference in energy levels involved in the transition.

b
The wavelength of a spectral line for an electronic transition is inversely proportional to the difference in the energy levels involved in the transition.

$\Delta E = E _2- E _1=\frac{ hc }{\lambda}$

$\lambda \propto \frac{1}{\Delta E }$
