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. Since the k-numbers are localised around a value k 0 we can do a Taylorseries of ω ( k): mtu hoster pc or macbookhttp://www-personal.umich.edu/~lorenzon/classes/2007/solutions/mPhys390-hw3-sol.pdf mtu holiday scheduleWebA "wave packet" can be used to demonstrate how either the momentum or position of a particle can be precisely calculated, but not both of them simultaneously.
