STANDARD Physics Hydrogen Spectrum MCQ Question
Type: MCQ-numerical-Medium-Class 11
If the wavelength of the first line of the Balmer series of hydrogen is 6561 Å, the wavelength of the second line of the series should be
A
13122 Å
B
3280 Å
C
4860 Å
D
2187 Å
Correct Answer
Option C
Detailed Explanation
For Balmer series, n₁ = 2, n₂ = 3 for 1st line and n₂ = 4 for second line. Using the formula for wavelength ratio, λ₂ = (20/27) × 6561 = 4860 Å.
