The frequency of radiation absorbed or emitted when transition occurs between two stationary states with energies $E_1$ (lower) and $E_2$ (higher) is given by
- A$v = \frac{E_1+E_2}{h}$
- B$v = \frac{E_1 - E_2}{h}$
- C$v = \frac{E_1 \times E_2}{h}$
- D$v = \frac{E_2 - E_1}{h}$

The energy of an electron in the first Bohr orbit of hydrogen atom is $-2.18 \times 10^{-18} \ J$. Its energy in the third Bohr orbit is $........$.
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 $\lambda_1: \lambda_2=$
Supposing the energy (in arbitrary units) of the energy levels in the hydrogen atom is given as under:
Energy level $K$ $(n=1)$ $L$ $(n=2)$ $M$ $(n=3)$ $N$ $(n=4...n=\infty)$ Energy $-864 \ a.u.$ $-216 \ a.u.$ $-96 \ a.u.$ $0 \ a.u.$
The excitation energy needed to raise the electron from $M$ level to $n = \infty$ would be:
| Energy level | $K$ $(n=1)$ | $L$ $(n=2)$ | $M$ $(n=3)$ | $N$ $(n=4...n=\infty)$ |
| Energy | $-864 \ a.u.$ | $-216 \ a.u.$ | $-96 \ a.u.$ | $0 \ a.u.$ |
The excitation energy needed to raise the electron from $M$ level to $n = \infty$ would be:
