In Compton effect, the incident photon when compared to the scattered photon is of:
Correct answer: C. Greater energy and momentum
- A. Greater energy
- B. Greater frequency
- C. Greater energy and momentum
- D. Equal energy
Explanation
The correct statement is C. Greater energy and momentum. In the Compton effect, the incident photon has greater energy and momentum compared to the scattered photon, as energy and momentum are conserved during the scattering process.

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.
