AIPMT MAINS 2011 Physics Bohr Model MCQ Question
Type: MCQ-conceptual-Medium-Class 11
According to the Bohr Theory, which of the following transitions in the hydrogen atom will give rise to the least energetic photon?
A
n = 6 to n = 5
B
n = 5 to n = 3
C
n = 6 to n = 1
D
n = 5 to n = 4
Correct Answer
Option A
Detailed Explanation
The energy of a photon is inversely proportional to the wavelength of the transition. The transition from n = 6 to n = 5 involves the smallest energy difference, thus emitting the least energetic photon.
