Bragg diffraction and Compton effect are two very different phenomena.eoghan said:

Well, the x-rays are not scattered by the block or graphite crystals in the block. They are scattered by the electrons in the graphite.eoghan said:But I've studied that Compton found the effect by the measurements of the x-ray frequencies scattered by graphite block, which is not a particle

I suspect that there is some Compton scattering. Whether Compton scattering occurs for a particular electron may depend on the way the electron is bound to the nucleus. If the energy imparted to the electron by the x-ray photon is less than the energy required to take it to the next energy level, the electron cannot take on the x-ray's energy, so there would not be any change in x-ray energy.eoghan said:
Compton scattering is a phenomenon in which a photon (or other elementary particle) collides with an electron, transferring some of its energy to the electron and causing it to scatter at a different angle. This effect was first observed by Arthur Compton in 1923 and is important in understanding the behavior of electromagnetic radiation.
In regular scattering, such as in the case of light reflecting off a mirror, the wavelength and energy of the scattered radiation remain the same as the incident radiation. However, in Compton scattering, the wavelength of the scattered radiation is longer and the energy is lower than the incident radiation due to the transfer of energy to the electron.
Bragg diffraction is a phenomenon in which a beam of X-rays or other waves is scattered in a specific pattern by a crystal or other regularly repeating lattice structure. This effect was discovered by father-son duo William and Lawrence Bragg in 1912 and is used in X-ray crystallography to determine the atomic structure of crystals.
Bragg diffraction occurs when the wavelength of the incident radiation is on the same order of magnitude as the spacing between the atoms in a crystal lattice. As the radiation is scattered, constructive interference between the waves reflected from different atomic planes results in a distinct diffraction pattern.
Compton scattering is used in various imaging techniques, such as Compton cameras for medical imaging and Compton telescopes for astronomical observations. Bragg diffraction is commonly used in X-ray crystallography to determine the structure of molecules and materials, as well as in X-ray spectroscopy to analyze the composition and properties of materials.
