356621 An electron jumps from \({4^{{\rm{th}}}}\) orbit to \({2^{{\rm{nd}}}}\) orbit of the hydrogen atom. Given, Rydberg's constant \(R = {10^5}\;c{m^{ - 1}}\), the frequency in hertz of emitted radiation will be

1 \(\dfrac{3}{16} \times 10^{5}\)
2 \(\dfrac{3}{16} \times 10^{15}\)
3 \(\dfrac{9}{16} \times 10^{15}\)
