Quantum
Photon Energy Calculator
Compute the energy of a single photon from its wavelength using E = hc/λ, the Planck-Einstein relation. Returns energy in joules; convert to electron-volts by dividing by 1.602 × 10⁻¹⁹.
Fill in the required fields to see your result.
Quantum
Compton Scattering Calculator
Compute the scattered photon's wavelength after Compton scattering off a free electron, given the initial wavelength and scattering angle. The wavelength shift demonstrates the photon's particle-like momentum exchange.
