Calculate the frequency of the light emitted by a hydrogen atom during a transition of its electron from the n = 3 to n = 1 energy level, based on the Bohr theory. Use the equation E_{n} = -2.18 x 10^{ -18} J [(1/n_{f}^{2})-(1/n_{i}^{2})]

a. 2.92 x 10^{15} s^{-1}

b. 3.56 x 10^{14} s^{-1}

c. 2.92 x 10^{14} s^{-1}

d. 1.17 x 10^{15} s^{-1}
