SUMMARY

The discussion centers on the nature of photons, specifically addressing whether they possess mass despite having momentum and energy. Participants assert that photons do not have mass, referencing established principles in physics. The conversation highlights the distinction between mass and the properties of momentum and energy, clarifying that the presence of momentum and energy in photons does not equate to mass.

PREREQUISITES
  • Understanding of basic physics concepts, particularly in relativity.
  • Familiarity with the definitions of mass, momentum, and energy.
  • Knowledge of the properties of photons in quantum mechanics.
  • Awareness of the Relativity FAQ as a resource for common physics questions.
NEXT STEPS
  • Research the implications of massless particles in quantum mechanics.
  • Study the relationship between energy and momentum in relativistic physics.
  • Explore the concept of mass in the context of Einstein's theory of relativity.
  • Examine the role of photons in electromagnetic theory and their behavior in different mediums.
USEFUL FOR

Students of physics, educators in the field of science, and anyone interested in the fundamental properties of light and its implications in modern physics.

Did you look on the Relativity FAQ list for the answer to this Frequently Asked Question?
 
Huh ?

A photon has momentum, and energy as well, this doesn't mean it has mass.
