Three energy levels of hydrogen atom and the corresponding wavelength of the emitted radiation due to different electron transition are as shown. Then
Three energy levels of hydrogen atom
An electron in an excited state of Li2+ ion has angular momentum \(\frac{3h}{2\pi}\). The de Broglie wavelength of electron in this state is Pπa0 (where a0 = Boh r radius). The value of P is
Energy of an electron in the second orbit of hydrogen atom is E2. The energy of electron in the third orbit of He+ will be
The ratio of area of first excited state to ground state of orbit of hydrogen atom is
