(4/24/20, bes)
Greetings,
- Congratulations for making it thru the week! Only 1.5 week left...or 5 more class periods...and one more lab.
EXAM 3 Announcement: Friday, May 1st (1 week from today) we will have Exam 3 (Ch 6 and 7) via WA. Just like last time, the WA-exam will be timed and available at 8 am. You may take the exam at anytime during the day, but once you open the assignment you have...60 mins...plus a BONUS 15 mins...75 min total. I want all exams completed by 5 pm, so you should start before 3:45 pm. If you know of a valid conflict please email to discuss.
- ...continuing with Chapter 7...
Sec 7.4/7.5: The Dual Nature of the Electron and Quantum Mechanics
Read/skim these sections.
As i noted when discussing the emission spectrum of the H-atom, there were many "molecular-type" experiments that were done that classical mechanics (standard physics) could not explain. Hence the rise of quantum mechanics (QM). The following video is a nice explanation of the "double-slit" experiment that highlighted the "dual nature" of the electron...and introduces you to a few QM concepts.
Dr Quantum Wave particle duality...and the double slit experiment
Sec 7.6: Quantum Numbers
Let's go back to a figure presented in lecture 2...
