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

A

Number of electrons undergoing transition

B

Nuclear mass of an atom

C

The difference of energy levels involved in transition

D

The velocity of the electron undergoing transition

Text Solution

Verified by Experts

The correct Answer is:
C
Smaller the energy difference between orbits lesser the energy released when the electron falls from a higher to lower orbit.
Lesser the energy higher the wavelength as per Planck’s Law `E = (hc)/(lamda) or E prop (1)/(lamda)`
