1. *Wave packet theory, describing the location of electrons, is a good example. 2. This wave packet becomes increasingly localized with the addition of many waves. 3. The superposition of several plane waves to form a wave packet . 4. The incoming wave packet , its tail extending ahead of it, approaches the chamber. 5. The wave that corresponds to a particle is a Wave packet . 6. One can, using them, express functions that " are " normalizable using wave packets . 7. For example, a common choice for " A " o is a Gaussian wave packet : 8. Phonons are constrained, quantized wave packets that travel at a given substance's speed of sound. 9. The main difference lies in the meaning of the reduction rule for wave packet collapse. 10. Because calculations for an infinite wave are deficient in second order, a wave packet is analysed.
