The Balmer series lies in the _ region.
Correct answer: B. Visible
- A. UV
- B. Visible
- C. Infrared
- D. None of the above
Explanation
Balmer series is displayed when electron transition takes place from higher energy states (nh=3,4,5,6,7,...) to nl=2 energy state. All the wavelength of Balmer series falls in the visible part of the electromagnetic spectrum (400nm to 740nm). You can use this mnemonic to remember the order of the electromagnetic spectrum: MyanMer Pasta Bread Fund. Lyman, Balmer, Paschen, Brackett, Pfund. We've also added a picture to help you remember the entire spectrum!

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.
