can wave particle duality be viewed at macroscopic scale...?? ok so far we have discussed the wave particle duality in case of electrons of-course at microscopic level through the 1) interference phenomenon showing its wave behavior 2)photoelectric effect discussing its particle characteristics..!! but we have discussed it at only microscopic level ...can it be possible to view this phenomenon at macroscopic level ...particularly wave behavior ...!! let take an example of a car how would we be proving its wave characteristics ...?????
