Which of the following is true?
Correct answer: B. the Paschen series is a line spectrum in the infrared region
- A. the Lyman series is a continuous spectrum
- B. the Paschen series is a line spectrum in the infrared region
- C. the Balmer series is a line spectrum in the ultraviolet region
- D. the spectral series formula can be derived from Rutherford's model of the hydrogen atom
Explanation
B is the correct option because The Paschen series consists of spectral lines in the infrared region of the electromagnetic spectrum. It represents transitions of electrons in hydrogen atoms from higher energy levels to the third 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.
