The discussion centers on the nature of light, specifically whether it propagates as a wave or a particle. A beginner posits that as the speed of a particle increases, its mass increases, suggesting that light behaves as a particle during propagation. However, it is established that light has zero rest mass, and thus the concept of "relativistic mass" does not apply in the same way. For accurate understanding, it is recommended to consult the Relativity FAQ subforum for further clarification.

Garvi said:Well, i am beginner with this topic. As the speed of particle increases its mass increases.thus i think that light emitted or radiated in form of wave and during propagation its velocity is high so it should behave as particle. Is it true and if not than what is true reason?
