An electron from various excited states of hydrogen atom emit radiation to come to the ground state. Let `lambda_(n),lambda_(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 emitted photon in the transition from the `n^(th)` state to the ground state. For large n, (A, B are constants)
A. `^^_(n)^(2)~~lambda`
B. `^^_(n)~~A+(B)/(lambda_(n)^(2))`
C. `^^_(n)~~A+Blambda_(n)`
D. `^^_(n)^(2)~~A+B lambda_(n)^(2)`
