Question

The series corresponding to minimum wave length transition in H-atom is

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

Answer 1

The correct option is B Lyman series

Lyman series corresponds to the highest energy or lowest wavelength transition $n\to 1$ transition; where, $n\ge 2$.

Energy of transition $=13.6eV\times (\frac{1}{n_f^2}-\frac{1}{n_i^2})$

For any given integer value of $n_i$, the energy of transition is greatest for $n_f=1$
