AIIMS 2019 Chemistry Hydrogen Spectrum MCQ Question
For balmer series, n¹ = 2 and n² = 3, 4, 5, 6,.........
In balmer series, four spectral lines are available in visible region.
These spectral lines have wavelengths greater than 400 nₘ and smaller than 700 nₘ.
Correct Answer
Detailed Explanation
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.
