Two energy levels of an electron in an atom are separated by \( 2.3 \mathrm{eV} \). The frequency of radiation emitted when the electrons goes from higher to the lower level is
[AMU (Engg.) 2010]
(a) \( 6.95 \times 10^{14} \mathrm{~Hz} \)
(b) \( 3.68 \times 10^{15} \mathrm{~Hz} \)
(c) \( 5.6 \times 10^{14} \mathrm{~Hz} \)
(d) \( 9.11 \times 10^{15} \mathrm{~Hz} \)
