Question

Which of the following series of transitions in the spectrum of hydrogen atom fall in the visible region?

• A. Balmer series
• B. Paschen series
• C. Brackett series
• D. Lyman series

Hint:

The Balmer series produces visible lines, while other series such as Lyman and Paschen produce ultraviolet and infrared lines, respectively.

Answer 1

The Correct Option is A

The Balmer series in the hydrogen atom spectrum corresponds to the transitions of electrons from higher energy levels to the second energy level (\(n = 2\)). These transitions produce light in the visible region of the electromagnetic spectrum. The wavelengths of these lines fall in the visible range, which is why they are observable as distinct colors in the spectrum. Thus, the correct answer is Option (A).
