MCQ
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
    $v = \frac{E_1 \times E_2}{h}$
  • ✓
    $v = \frac{E_2 - E_1}{h}$
✓

Answer

Correct option: D.
$v = \frac{E_2 - E_1}{h}$
d
$\mathrm{h} v=\mathrm{E}_{2}-\mathrm{E}_{1}$

$v=\frac{E_{2}-E_{1}}{h}$
