Energy of an electron is given byE=−2.178×10−18J(Z2n2) wavelength – InterviewSolution

1.	Energy of an electron is given byE=−2.178×10−18J(Z2n2) wavelength of light required to excite an electron in an hydrogen atom from level n = 1 to n = 2 will be(h=6.62×10−34 J s and c=3.0×108m s−1)
Answer» Energy of an electron is given by $E = - 2.178 \times 10^{- 18} J (\frac{Z^{2}}{n^{2}})$ wavelength of light required to excite an electron in an hydrogen atom from level n = 1 to n = 2 will be $(h = 6.62 \times 10^{- 34} J s a n d c = 3.0 \times 10^{8} m s^{- 1})$
