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.
