Light prapogate as wave or particle?

  1. Jun 21, 2012 #1
    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 propogation its velocity is high so it should behave as particle. Is it true and if not than what is true reason?

    Your understanding of Special Relativity is faulty, and thus, your application of it is invalid.

    Light has ZERO rest mass. Thus, even accepting the flaky concept of "relativistic mass", the relativistic mass of a "particle" that has zero rest mass is STILL zero!

    Read the Relativity FAQ subforum in the Relativity Forum.
