The potential difference applied to an X-rays tube is increased. As a result, in the emitted radiation
Correct answer: D. both b & c
- A. the intensity increases
- B. the intensity remains unchanged
- C. the minimum wavelength decreases
- D. both b & c
Explanation
D is the right option Here's why: When the potential difference applied to an X-ray tube is increased, both the intensity of the emitted radiation and the minimum wavelength decrease. This is because the higher potential difference accelerates the electrons more, leading to higher-energy X-rays with shorter wavelengths.

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.
