Question

The wavelength of the  line of the Balmer group for the hydrogen spectrum is

Quizplus · Accepted Answer

The Balmer series is a series of hydrogen spectral lines produced by electron transitions from energy levels n ≥ 3 to n = 2. The 11ea821f_c64c_2fc1_bbd8_791f6eb945fc_TB1516_11_TB1516_11_TB1516_11 line corresponds to the transition from n = 4 to n = 2. The formula for calculating the wavelength of these lines is λ = 1.097 × 10^-2 (1/2^2 - 1/n^2), where n is the energy level of the electron. Plugging in n = 2 and n = 4, we get λ = 434 nm. Therefore, the correct answer is D.
