21. The basic idea is that the environment registering the detection effectively separates the two wave packets in configuration space. 22. The narrow-width limit of the Gaussian wave packet solution discussed is the free " "'propagator kernel " " '. 23. The nondispersive propagation of the real or imaginary part of this wave packet is presented in the above animation. 24. In the quantum theory, photons are seen as wave packets of the waves described in the classical theory of Maxwell. 25. To localize a particle, de Broglie proposed a superposition of different wavelengths ranging around a central value in a wave packet , 26. If V g is the group velocity of a phonon wave packet , then the relaxation length l \; is defined as: 27. The peaks of one wave packet overlap the troughs of the other, so they cancel each other out and nothing remains. 28. However, the wave packet will also spread out as time progresses, which means that the position becomes more uncertain with time. 29. My perception of a wave packet coincides with the image " Wave _ packet _ ( dispersion ) . gif . ". 30. Apart from one single rogue wave, the rogue wave may be part of a wave packet consisting of a few rogue waves.
