STANDARD Physics Bohr's Model MCQ Question

Type: MCQ-conceptual-Medium-Class 11

An electron in a hydrogen atom makes a transition from n = n₁ to n = n₂. The time period of the electron in the initial state is eight times that in the final state. The possible values of n₁ and n₂ are

A

n₁ = 4, n₂ = 2

B

n₁ = 8, n₂ = 2

C

n₁ = 8, n₂ = 1

D

n₁ = 6, n₂ = 2

Correct Answer

Option A

Detailed Explanation

The time period Tₙ is proportional to n³. If T₁/T₂ = 8, then (n₁/n₂)³ = 8, which implies n₁/n₂ = 2. Thus, n₁ = 4 and n₂ = 2.
