The ratio of wavenumber of first line of Balmer series and wavenumber of second line of Lyman series of hydrogen atom is:

Energy of orbit X of Li$^{2+}$ is $-2.18\times10^{-18}$ J. Find radius of same orbit (in Å).}

Observe the following statements
Statement-I: Rutherford model of an atom cannot explain the stability of an atom
Statement-II: The wavelength of X-rays is higher than the wavelength of microwaves
The correct answer is

In the atomic spectrum of hydrogen, the wavelengths of the spectral lines corresponding to electronic transitions (i) n = 4 to n = 2 and (ii) n = 3 to n = 1 are $\lambda_1$ and $\lambda_2$ \AA{}respectively. The value of $(\lambda_1 - \lambda_2)$ (in cm) is ($R_H$ = Rydberg constant)

The energy associated with electron in first orbit of hydrogen atom is \(-2.18 \times 10^{-18}\) J. The frequency of the light required (in Hz) to excite the electron to fifth orbit is (\(h=6.6 \times 10^{-34}\) Js)
