Physics 290 Fall 2016 Homework #5
Due in class Friday October 7th.
1) I pointed out in class that the uncertainty principle implies a certain minimum momentum for an electron that is
confined to stay close to a nucleus. Lets explore this a little more.
Physics 290 Fall 2016 Homework #9
Due in class Friday Nov 4th.
1) Two physicists measure the rate of decay of a long-lived radioactive source. Physicist A monitors the sample for
four hours and observes 412 decays. Physicist B monitors it for 6 hours an
Physics 290 Fall 2016 Homework #10
Due in class Friday Nov 18th.
1) Compare the de Broglie wavelengths of a 2 keV photon and a 2 keV electron. Repeat the comparison for 200 keV
photons and electrons and then finally for 20 MeV photons and electrons.
Physics 290 Fall 2016 Homework #2
Due Friday September 9th.
1) A beam of UV light of wavelength = 197.0 nm falls onto a metal cathode. The stopping potential needed to
keep any electrons from reaching the anode is 2.08 V .

Physics 290 Fall 2016 Homework #7
Due in class Friday October 21st.
1) Use the idea that a rough order of magnitude guess at the probability of tunneling through a barrier is given by
ratio of the de Broglie wavelength to the thickness of the barrier to
Physics 290 Fall 2016 Homework #1
Due Friday September 2nd.
NOTE: To get a good grade, your answers must not only be correct but must very clearly demonstrate that they are
correct. This can mean clear explanations and good diagrams in addition to any cal
Physics 290 Fall 2016 Homework #4
Due by 5 pm Friday September 23rd.
1) If I confine you to the back room of the lab, roughly 10m long and narrow enough that we can approximate it as
1-D, then Heisenber says that your momentum must be uncertain. Calcula

1) Under controlled laboratory conditions, a human eye can see light with an intensity as low as 1.3 1013 W/m2 .
Using a reasonable assumption about the area of the iris of the eye
Physics 290 Fall 2016 Homework #6
Due in class Wednesday October 12th.
In class we solved the infinite square well in a coordinate system where the well
ran from x=0 to x=L. In that case we found wave functions of the form sin
