Compton Scattering Calculator
Calculate photon energy and wavelength changes in Compton scattering events
About this calculator
The Compton Scattering Calculator computes the energy and wavelength changes of photons when they collide with electrons in matter. This fundamental quantum mechanical process occurs when high-energy photons (like X-rays or gamma rays) transfer some of their energy to electrons, resulting in scattered photons with lower energy and longer wavelengths. This calculator is essential for physics students, researchers, and professionals working in medical imaging, nuclear physics, and radiation therapy to predict photon behavior in materials.
How to use
Enter the initial photon energy or wavelength and specify the scattering angle (angle between incident and scattered photon directions). The calculator will automatically compute the final photon energy, wavelength, and the energy transferred to the electron using the Compton scattering formula. Results help analyze photon-electron interactions in various materials.
Frequently asked questions
What is Compton scattering?
Compton scattering is the inelastic collision between a photon and an electron, where the photon loses energy and changes direction while the electron gains kinetic energy.
When does Compton scattering occur?
Compton scattering primarily occurs with high-energy photons (X-rays and gamma rays) when photon energy is comparable to or greater than electron rest mass energy.
What factors affect the energy change?
The energy change depends on the initial photon energy and scattering angle. Larger scattering angles result in greater energy loss by the photon.
