The wavelngth fo a spectrl line for an electronic transition is inversely related to :

Options

A. Thenumber of electron undergoing the transition
B. The nuclear charge of the atom
C. The difference in the energy of the energy7 levels involoved in the transition
D. The velocity of the undegoing the transition

Answer

C

Explanation

`E = hv and Delta E = (hc)/(lambda)`
The wavelength of a spectral line for an electronic transition is involving related to the difference in the energy of the energy levels involved in the transition
