PH253: HW4 is out

Here you are. As usual, we will do a number of them in class. A couple of quick notes in advance of more substantial hints:

• For number 3, you will need to look up the intensity pattern for single-slit diffraction. Presume the electron must be confined within the central, most intense region, which gives you an estimate of position uncertainty.
• I've asked number 6 before.
• Number 7 is a famous thought experiment, it can be found in the wikipedia article on the uncertainty principle.
• Number 8 is a straight math problem (math we'll need soon). Don't let the the unfamiliar terms stump you, all you need to do is integration and algebra for parts a-c.

UPDATE: fixed a few typos, in particular on number 8.
