Doubts about wave particle duality I know that a wave packet is formed by superposition of several individual waves having different wavelength.And the resultant wave has varying amplitudes.And from these amplitudes we can find the likeliness of the object to be in that position. My doubt is how can there be many waves of different wavelength associated with an object. I mean by debroglies hypothesis λ=h/mv. So there should only be one long indefinite probability wave analogous to a cosine wave.(Where do so many waves come from?from the same object?) Or is it this way- I want to find the resultant wave packet of a baseball. So i individually take all the atoms,electrons of the baseball, find their wavelength individually,and then add these waves(Superposition)? then will i get a proper wave,with varying amplitudes?
