Chemistry - Atomic Structure Question with Solution | TestHub

Let us assume that de-Broglie equation is valid in Bohr model. In H-like sample, an electron is in an orbit which has path length of the orbit is equal to 3 times of wavelength of electrons in that orbit. This orbit of H-like sample has total energy equal to the ground state energy of H-atom. Now we have same sample having all electrons in the ground state. If photon of energy 126.566 eV is given to this ground state sample then approximate value of wavelength ( $\lambda$ )(in $\mathring{A}$, closest integer) of ejected ${\mathrm{e}}^{-}$is :
