Q1

The frequency of radiation emitted when the electron falls from n = 4 to n = 1 in a hydrogen atom will be (Given : ionization energy of \(\mathrm{H}=2.18\times {10}^{-18}\mathrm{J}/\mathrm{atom}\mathrm{and}\mathrm{h}=6.625\times {10}^{-34}\mathrm{Js}\))

a

\(1.54\times {10}^{15}{\mathrm{s}}^{-1}\)

b

\(1.03\times {10}^{15}{\mathrm{s}}^{-1}\)

c

\(3.08\times {10}^{15}{\mathrm{s}}^{-1}\)

d

\(2.00\times {10}^{15}{\mathrm{s}}^{-1}\)
