SUMMARY

A photon is a fundamental particle of light, recognized as both a wave and a particle due to phenomena such as the photoelectric effect and Compton effect. Historically, light was classified solely as an electromagnetic wave until the early 20th century when its particle nature was established. Photons are massless and exhibit behaviors like diffraction and interference. For further exploration, refer to the informative threads on Physics Forums, particularly the one linked in the discussion.

PREREQUISITES
  • Understanding of the photoelectric effect
  • Familiarity with the Compton effect
  • Basic knowledge of wave-particle duality
  • Concepts of diffraction and interference
NEXT STEPS
  • Research the photoelectric effect in detail
  • Explore the Compton effect and its implications
  • Study wave-particle duality in quantum mechanics
  • Investigate the principles of diffraction and interference in light
USEFUL FOR

Students of physics, educators, and anyone interested in the fundamental properties of light and quantum mechanics.

Does anybody know what a photon is? Light used to be known as electromagnetic wave till 1900, but then it's particle was made justified by photoelectric effect, Compton effect. And we know about diffraction, interference, etc. And it has no mass.
