Scientists believe that light is made of streams of particles because light exhibits the particle nature. This can be explained on the basis of photoelectric effect observed when light is made to fall on the surface of a metal. when light falls on the surface of a metal, it makes the electron to eject out. This is possible only when light consists of small particle called photons. hence the scientists believe that light is made of streams of particles.
