Photons, by definition, exhibit both properties of waves and particles. But here too a clear definition of particle is lacking. Physicists say photons are quanta, and use quanta and particles as synonyms. Photons have zero mass so they don’t have a finite radius as miniture billard balls. So, we have no idea what Victor sends. By convention he sends “particles” and we are forbidden to ask how this word particle is defined. A good example showing that physics is done by authority.
