Question

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

• A. Number of electrons undergoing transition
• B. The nuclear charge of the atom
• C. The velocity of an electron undergoing transition
• D. The difference in the energy involved in the transition

Answer 1

Answer: (D)

The difference in the energy involved in the transition

Answer 2

$\lambda = \frac{hc}{\Delta E}\therefore\lambda\alpha\frac{1}{\Delta E}$
