Particle Nature of Matter

  1. Photoelectric Effect

In the photoelectric effect, it was shown that when light falls on a surface, electrons are emitted from the surface. Similarly, when X-ray is allowed to fall on the surface of a thin sheet of metal like gold, the X-ray not only produces diffraction pattern but also acting like particles they may collide with the atoms of the metal and eject electrons as in the photoelectric effect.
