In Compton's scattering process, the wavelength of scattered X-rays:
Correct answer: B. Increases
- A. Remains the same
- B. Increases
- C. Decreases
- D. None of these options are correct
Explanation
In Compton scattering, the wavelength of the scattered X-rays increases. This occurs because the photon loses energy to the electron during the scattering process. The increase in wavelength is directly proportional to the increase in the scattering angle.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
