Imagine an atom made of a nucleus of charge (Ze) and a hypothetical particle of same mass but double the charge of the electron. Apply the Bohr atom model and consider all possible transitions of this hypothetical particle to the ground state. The longest wavelength of photon that will be emitted has wavelength λ (Given in terms of Rydberg constant R of hydrogen atom) equal to –
