STANDARD Physics Spectral Series MCQ Question

Type: MCQ-conceptual-Medium-Class 11

If v₁ is the frequency of the series limit of Lyman series, v₂ is the frequency of the first line of Lyman series and v₃ is the frequency of the series limit of the Balmer series, then

A

v₁ − v₂ = v₃

B

v₁ = v₂ − v₃

C

1/v₂ = 1/v₁ + 1/v₃

D

1/v₁ = 1/v₂ + 1/v₃

Correct Answer

Option A

Detailed Explanation

For the Lyman series, v₁ is the series limit and v₂ is the first line. For the Balmer series, v₃ is the series limit. The relationship v₁ − v₂ = v₃ holds based on the Rydberg formula.
