QUESTION #7359
Question 1
The smallest wavelength among spectral series of hydrogen occurs in which series?
Correct Answer Explanation
Concept: Wavelength \(\propto \dfrac{1}{\Delta E}\). Smallest wavelength = largest energy transition.
The Lyman series (\(n \geq 2 \to n=1\)) involves transitions to the lowest energy level, releasing the most energy. The series limit of Lyman series gives the shortest possible wavelength (91.2 nm in UV region).
Order of wavelengths: Lyman < Balmer < Paschen < Brackett
