Which X-ray photon will have the longest wavelength?
Correct answer: D. M series
- A. K alpha
- B. K beta
- C. K gamma
- D. M series
Explanation
M X-ray photons will have the longest wavelength because they correspond to transitions involving lower energy differences compared to Kα, Kβ, and Kγ photons.

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.
