Modern Physics

the week of March 18 - 19

this week's readings

    Thursday,  Mar 18        read 2.5 about x-rays up to the Compton effect
                                        make sure that you know the 2 pieces of evidence
                                            for x-rays behaving like particles
                                        (you may have to read another section in the book
                                        to understand everything completely)

    Friday, Mar 19              for class, read Cutnell and Johnson section 27-8 and all of the
                                            lab handout
                                        do Modern Physics Lab 5: Measuring the Wavelength of Light

    Monday, Mar 22            finish reading section 2.5 on the Compton effect

                                        bring to class:  a print-out of your best function fit
                                                    to the current-vs-voltage plots from the photoelectric
                                                    effect data...
                                        you should bring at least one for each color (and you should
                                                    have tried more functions than the one (best) that you
                                                    bring; you must use the same function for all light colors


this week's assignments

    Thursday, Mar 18        have you been to your dentist???

                                        start working on your modeling of the current-vs-voltage data
                                            from the photoelectric experiment.... find an appropriate
                                            modeling function and bring printed copies to class monday
                                            of your function fit to several i-vs-v plots
