Balmer series lies in that region of electromagnetic wave spectrum, which is known as:
Correct answer: A. Visible region
- A. Visible region
- B. Ultraviolet region
- C. Invisible region
- D. lnfra-red region
Explanation
The Balmer series corresponds to the set of spectral lines in the emission spectrum of hydrogen atoms that result from electron transitions within the atom involving the principal quantum number "n" ranging from 3 to higher levels down to n = 2. These transitions result in the emission of photons with specific energies. The Balmer series is located in the visible region of the electromagnetic spectrum, which ranges from approximately 400 to 700 nanometers (nm). It includes colors that are visible to the human eye.

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.
