Atomic Model and Wave-Particle Duality

i.e.Wave PacketThe probability of finding the ‘particle’ atany point in space is proportional to theabsolute square of the amplitude of thecorresponding de Broglie wave at the point.probability ~ |Ψ| 2 ~ |A| 2In the wave-packet description, the probability of finding theparticle is large in the central region of size Δx where thewave amplitude is large, while it is small outside!Note that the amplitude of the matter-wave has no physicalmeaning!77
