SUMMARY
Photons are classified as massless particles, yet they possess momentum due to their energy and the principles of quantum mechanics. According to Einstein's theory of relativity, momentum is defined as the product of mass and velocity; however, for photons, the equation is modified to include energy, expressed as p = E/c, where p is momentum, E is energy, and c is the speed of light. This relationship allows photons to exert pressure and interact with matter despite having no rest mass.
