Vedclass · Answer

(B) wave packet is a short 'burst' or 'envelope' of wave action that travels as a unit. In quantum mechanics,a single de Broglie wave (monochromatic wave) extends infinitely in space,which makes it impossible to localize a particle. To represent a particle localized in space,we superimpose a group of waves with slightly different wavelengths and frequencies. This superposition results in constructive interference over a small region of space and destructive interference elsewhere,creating a localized 'packet' of waves. Thus,a wave packet represents the probability distribution of finding a particle at a specific position.
