Self study 1
1. Sketch a Gaussian function, including labelling its turning points and its characteristic width. 2. State an expression for a Gaussian wave packet. 3. Demonstrate mathematically that a Gaussian wave packet can be represented as a linear combination of freeparticle wave functions, and such a linear combination includes a range of momenta consistent with the uncertainty principle.
