Four students are discussing whether particles can act as waves.

Which of the following statements and reasons below is correct?


Student One says that particles cannot exhibit wavelike behavior because if two automobiles meet on a highway, they do not continue on without change after the collision such as is observed with wave interference.


Student Two says that particles cannot act like waves because the required momentum would be too small. The masses must have speeds that are too high to attain.


Student Three says that particles can act like waves because when playing pool, the balls hitting the sides obey the law of reflection which is only true if it is acting like a wave.


Student Four says that particles can act like waves when the particles have a very small mass and a high speed.
