AIIMS 2019 Physics Hydrogen Spectrum MCQ Question

In the Balmer series of hydrogen, transitions occur from higher energy levels (n² = 3, 4, 5, 6, ...) down to n¹ = 2, resulting in visible spectral lines with wavelengths between approximately 400 nm and 700 nm. This range corresponds to the visible spectrum, confirming that option B is accurate. Option A is misleading because while there are four visible lines (from n² = 3 to n² = 6), the series actually includes more transitions, resulting in additional lines beyond just four. Options C and D are not applicable as they do not provide relevant information.
