Bohr S Model Of Hydrogen Atom

According to the question,
Energy given to hydrogen atom Difference in energy level from
to states

The wavelength of emitted radiation in hydrogen-like atoms is given by: where: - is the Rydberg constant, - and are the initial and final energy levels. 1. For transition : 2. For transition : 3. Ratio of Wavelengths: Thus, the correct answer is .
