Hög<bos> foton, or high-energy photons, are electromagnetic radiation with very short wavelengths and high frequencies. This means they carry a significant amount of energy per photon. In the electromagnetic spectrum, high-energy photons are found at the higher energy end, typically including ultraviolet radiation, X-rays, and gamma rays. The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength, as described by Planck's equation.

These high-energy photons interact strongly with matter. Their high energy allows them to penetrate materials that would absorb or reflect lower-energy photons. This property makes them useful in applications such as medical imaging (X-rays) and cancer therapy (gamma rays). High-energy photons can also cause ionization, which is the process of removing electrons from atoms or molecules, leading to chemical changes and potential damage to biological tissues.

Sources of high-energy photons are diverse. Stars, particularly supernovae and active galactic nuclei, are powerful natural sources of gamma rays. On Earth, high-energy photons are generated in particle accelerators and through radioactive decay processes. Understanding the properties and interactions of high-energy photons is crucial for fields ranging from astrophysics and nuclear physics to medicine and materials science.
