Correct answer: C. Option C
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The Paschen series, which represents spectral lines in the emission spectrum of hydrogen, can be described by the Rydberg formula, just like other hydrogen spectral series. The Rydberg formula for the Paschen series is: 1/λ = R_H * (1/3^2 - 1/n^2), For the Paschen series, the electron transitions from energy levels with n > 3 to the n = 3 energy level. This series is typically observed in the infrared part of the electromagnetic spectrum. The specific wavelengths of the lines in the Paschen series can be calculated using this formula, and they correspond to different values of the principal quantum number (n) in the final energy level.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
