Calculate the frequency of the photon, which can
\( \mathrm{P} \)
excite the electron to \( -3.4 \mathrm{eV} \) from \( -13.6 \mathrm{eV} \) :
W
(1) \( 2.47 \times 10^{15} \mathrm{~Hz} \)
(2) \( 5.85 \times 10^{15} \mathrm{~Hz} \)
(3) \( 1.45 \times 10^{15} \mathrm{~Hz} \)
(4) \( 3.5 \times 10^{15} \mathrm{~Hz} \)
