STANDARD Physics Bohr's Model MCQ Question
Type: MCQ-conceptual-Medium-Class 11
In which of the following Bohr's orbit (n) a hydrogen atom emits the photons of lowest frequency?
A
n = 2 to n = 1
B
n = 4 to n = 2
C
n = 4 to n = 1
D
n = 4 to n = 3
Correct Answer
Option D
Detailed Explanation
The energy level diagram shows that as we move to higher levels, the energy increases, but the energy gap between levels decreases. In the transition from n = 4 to n = 3, the energy released is E₄ - E₃, which is less than E₂ - E₁. Thus, the frequency of the photon emitted is lowest for n = 4 to n = 3.
