Photon Momentum



Photon momentum is a concept in physics that deals with how light (photons) — though massless — still carries momentum due to its wave-particle duality.


Wave-Particle Duality



  • Photon behaves as both a wave and a particle.

  • Light waves can exert radiation pressure due to their momentum.


Applications:



  • Photoelectric Effect

  • Compton Scattering

  • Laser Physics

  • Radiation Pressure in Astrophysics

  • Solar Sail Propulsion


Photon Momentum Is Part Of :



  • Modern Physics

  • Quantum Mechanics

  • Electrodynamics

  • Relativistic Mechanics (since photons move at speed of light)
