The energy difference of two stable orbits of Hydrogen is $214.68 \ kJ \ mol^{-1}$. If the transition of an electron takes place,find the emitted frequency. (Note: $v = \Delta E/h$ and $h = 6.626 \times 10^{-34} \ J \ s$)
- A$5.39 \times 10^{14} \ Hz$
- B$3.57 \times 10^{14} \ Hz$
- C$8.21 \times 10^{14} \ Hz$
- D$1.24 \times 10^{14} \ Hz$
