AIIMS 2019 Chemistry Bohr Model MCQ Question

For the He⁺ ion, which is a hydrogen-like atom with Z = 2, the wavelength of emitted or absorbed light can be calculated using the Rydberg formula. Given n = 2, the energy levels can be determined, and the wavelength can be derived from the transition between energy levels, leading to a specific wavelength value. Since option B corresponds to the correct wavelength derived from these calculations, it is the right choice, while the other options do not provide relevant wavelength values or calculations for the He⁺ ion. Understanding the relationship between energy levels and wavelength in hydrogen-like ions is crucial for mastering atomic physics concepts.
