Re: Midterm
We will be taking the midterm on the respondus lockdown browser during our next discussion section with our TA proctoring and watching our work space therefore I believe it is a closed note test. It is multiple choice however so that is good :)

Re: n1 and n2
N1 is the final and N2 is the initial energy level of the electron. I find this very confusing so I would suggest memorizing the equation using nf and ni to denote final and initial positions of the electron :)

Re: Derivation of Equations on Midterm?
We definitely will not need to be able to show derivations on the test, especially with it being multiple choice. I believe he goes over derivations in lecture just to give us a better understanding of each equation and where it comes from :)

Re: How are you studying?
I’m studying by just looking over lecture notes every night to reinforce the material as well as do as many practice problems as possible :)

Re: Black Body Radiation
I don’t think we need to know anything about black body radiation, I believe the discussion with regards to black body radiation was just extraneous material.

Re: protons and electrons
Protons have a mass of 1 AMU whereas electrons are considered to have a negligible mass.

Re: unexpected outcome of wave-particle experiment
The unexpected outcome was the fact that even low frequency waves at very high intensities did not cause an electron to be released from the metal.

Re: Tutoring? [ENDORSED]
I wouldn’t pay for a tutor when Dr Lavelle has provided so many free resources for those struggling with their chemistry. If after using those resources you still feel bad then I would look into a tutor.

Re: Rusty on High School Chem [ENDORSED]
I would suggest utilizing the wealth of resources Dr Lavelle has such as step up sessions and office hours if you are not feeling confident on your chemistry :)

Re: Textbook
I’d suggest utilizing the free trial Dr Lavelle has setup to access sapling for the time being.

Re: Office hours vs. step up sessions
I believe Dr. Lavelle said that step up sessions are for people that are most struggling whereas office hours are for people with a bigger grasp on the material.
