Answer» According to Bohr theory, the electronic energy of the hydrogen atom in the $n^{t h}$ Bohr orbit is given by $E_{n} = - \frac{21 \times 10^{- 19}}{n^{2}} \times Z^{2} J$ The longest wavelength of light that will be needed to remove an electron from the $3^{r d}$ orbit of the $H e^{+}$ ion is $x \times 10^{- 7} m$ . Find the value of $x$ . (Give your answer upto two decimal only, take $h = 6 \times 10^{- 34} J s e c$ )
