STANDARD Chemistry Hydrogen Spectrum MCQ Question
Type: MCQ-numerical-Medium-Class 11
The shortest wavelength in the Balmer series is (R = 1.097 × 10⁷ m⁻¹)
A
200 nm
B
256.8 nm
C
300 nm
D
364.6 nm
Correct Answer
Option D
Detailed Explanation
Wavelength for Balmer series is given by 1/λ = R(1/2² - 1/n²). For the shortest wavelength, n = ∞, giving λ = 364.6 nm.
