AIPMT MAINS 2012 Physics Atomic Spectra MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The transition from the state n = 3 to n = 1 in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from:
A
2 → 1
B
3 → 2
C
4 → 2
D
4 → 3
Correct Answer
Option D
Detailed Explanation
Infrared radiation corresponds to smaller energy transitions. The transition from n = 4 to n = 3 involves less energy than from n = 3 to n = 1, thus emitting infrared radiation.
