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

A

The number of electrons undergoing the transition

B

The nuclear charge of the atom

C

The difference in the energy of the energy levels involved in the transition

D

The velocity of the electron undergoing the transition

Text Solution

Verified by Experts

The correct Answer is:
C
If wavelength is `lamda` then
`DeltaE=(hc)/lamda`
`lamda=(hc)/(DeltaE)rArrlamdaprop1/(DeltaE)`.
