The maximum energy is present in any electron at

If the wavelength of an electromagnetic radiation is $2000 \ \text{Å}$,what is its energy in ergs?

As an electron moves away from the nucleus,its energy:

The postulate of Bohr theory that electrons jump from one orbit to the other,rather than flow,is according to:

If the energies of two light radiations $E_1$ and $E_2$ are $25 \ eV$ and $100 \ eV$ respectively,then their respective wavelengths $\lambda_1$ and $\lambda_2$ would be in the ratio $\lambda_1: \lambda_2=$

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