Correct answer: C. The change in the wavelength of X-rays when they interact with matter
- A. The scattering of the light by prism
- B. The bending of light when it passes from one medium to another
- C. The change in the wavelength of X-rays when they interact with matter
- D. The creation of interference patterns in a double-slit experiment
Explanation
The Compton effect is a phenomenon in physics where the wavelength of X-rays or gamma rays changes when they interact with matter, specifically when they scatter off electrons. This effect is named after Arthur Compton, who first observed it in 1923.When X-rays or gamma rays interact with electrons, some of their energy is transferred to the electrons, causing the wavelength of the radiation to increase (or shift towards the red end of the spectrum). This effect is a result of the conservation of energy and momentum in the interaction between the radiation and the electrons.

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.
