Compton's effects was presented by: ________?
Correct answer: C. Arthur Holly Compton
- A. Mosely
- B. Marley
- C. Arthur Holly Compton
- D. Stefan Boltzman
Explanation
Arthur Holly Compton explained the scattering of X-rays by electrons using the photon model and showed that the scattered wavelength changes because photons transfer energy and momentum. Students may choose Stefan-Boltzmann because he is also associated with radiation, but his law concerns thermal emission rather than Compton scattering.

About Photons and the Particle Model of Light
The particle model treats light as photons with energy E equals hf and momentum related to wavelength. Questions involve the photoelectric effect, work function, threshold frequency, stopping potential and photon energy, while distinguishing particle behaviour from the wave description of interference and diffraction.
