Webcomparing with 7). The wave packet at t=0 is therefore a Gaussian centred at x=0. As tincreases, wgets smaller but the centre of the Gaussian does not move from x= 0 so the packet spreads out. Fig. 1 shows j (x;t)j2 for 3 values of w, showing how the wave packets spreads as tincreases (and thus wdecreases).

WebWave packets are usually peaked around a certain frequency ω 0 and hence around a certain wave number k 0, by doing this you can make for example a Gaussian out of your basefunctions which is mostly used for particles that are localised within an area.
