１８ Material wave（de Broglie wave）【What is the Universe？】Dialogue with the Universe
：On a submicroscopic level, there is no boundary strict between particles and wave.
→When existence is regarded as a wave motion, in physics, it is called a "place." For example, light is wave motion of an electric field and magnetic field.
※ It is under a very microscopic situation like an electron beam that the character as a wave is actually observed.
