An electron from various excited states of hydrogen atom emit radiation to come to the ground state . Let `lamda _(n) , lamda _(g) ` be the de Broglie wavelength of the electron in the n- th state and the ground state respectively .Let `^^ _(n) ` be the wavelength of the emited photon in teh transition from the n - th state to the ground state . for large n , ( A, B are constants )

Options

A. `^^ _(n ) ~~ A + B lamda _(n ) ^(2)`
B. `^^ _(n )^(2) ~~ lamda `
C. `^^ _(n ) ~~ A +(B )/(lamda _(n ) ^(2))`
D. `^^ _(n ) ~~ A +B lamda _(n) `
