In an electronic transition, atom cannot emit:
Correct answer: A. y-rays
- A. y-rays
- B. Visible light
- C. Infrared radiation
- D. Ultraviolet rays
Explanation
In an electronic transition the maximum energy photon can be emitted in x-ray region. y-rays can only be emitted in nuclear transition.

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.
