NEET 2025 Chemistry Wavelength Ratios MCQ Question

Type: MCQ-numerical-Easy-Class 11

The ratio of the wavelengths of the light absorbed by a Hydrogen atom when it undergoes n = 2 → n = 3 and n = 4 → n = 6 transitions, respectively, is

A

1/36

B

1/16

C

1/9

D

1/4

Correct Answer

Option D

Detailed Explanation

Using the Rydberg formula, the wavelength ratio is determined by the inverse of the square of the difference in energy levels. The ratio is (1/3² - 1/2²) / (1/6² - 1/4²) = 1/9.
