What is the type of characteristic X-ray photon whose energy is given by relation 'hf =EM - EK'?
Correct answer: C. K - beta
- A. K - alpha
- B. M - alpha
- C. K - beta
- D. M - beta
Explanation
When electrons from the M shell jump to occupy the hole in the K shell, the photons emitted are K-beta, and the energy emitted is hf = EM - EK

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.
