OBSERVED PHENOMENON. “Contrary to this prediction of classical physics, observations show that when X-rays are scattered off some materials, such as graphite, the scattered X-rays have different wavelengths from the wavelength of the incident X-rays.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

EXPECTED PHENOMENON. “By classical theory, when an electromagnetic wave is scattered off atoms, the wavelength of the scattered radiation is expected to be the same as the wavelength of the incident radiation.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

SUMMARY. “The Compton effect is the term used for an unusual result observed when X-rays are scattered on some materials.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

ADDITIONAL FACTOR. “Notice that this equation gives us only the magnitude of the photon’s momentum and contains no information about the direction in which the photon is moving. To include the direction, it is customary to write the photon’s momentum as a vector.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

PHOTON TRAITS. “A photon can be equivalently characterized by either its energy and wavelength, or its frequency and momentum. (Figure) and (Figure) can be combined into the explicit relation between a photon’s momentum and its wavelength.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

OBSERVATION. ‘One peak is located at the wavelength which is the wavelength of the incident beam. The other peak is located at some other wavelength, The two peaks are separated by which depends on the scattering angle of the outgoing beam (in the direction of observation). The separation is called the Compton shift.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

PARADIGM SHIFT. “The explanation of the Compton effect gave a convincing argument to the physics community that electromagnetic waves can indeed behave like a stream of photons, which placed the concept of a photon on firm ground.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn
