Standard Books Chemistry Hydrogen Spectrum MCQ Question with Solution

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

Option D

Wavelength for Balmer series is given by 1/λ = R(1/2² - 1/n²). For the shortest wavelength, n = ∞, giving λ = 364.6 nm.
