Re: Wavelength/frequency
Because E=hc/lambda wavelength is the denominator and the greater the wavelength means the less energy you have since the variables h and c are constants.

Re: Energy vs Intensity
Energy is usually used to describe the overall energy of a wave while intensity is usually used to describe the power per square meter.

Re: Keywords for Work Function or E_photon?
One of the keywords you should be looking for is threshold energy, if this comes up in the problem being asked you know you will not be solving for the e photon. If you see wavelength then you know you will be solving for e photon.

Re: Bohr radius [ENDORSED]
I don't think that will be important for this midterm I wouldn't worry too much about it.

Re: Shapes of orbitals
No I don't think you will need to know the shape of every orbital but I would go over them just in case since they will come into play later in the class.

Re: Memorizing formulas test 2
All the formulas should be given, focus on knowing how to use them instead.

Re: Significant Figures When Multiplying and Dividing [ENDORSED]
You need the same amount of sig figs in order to be able to multiply or divide.

F19
For this problem on the homework do you divide the percentage of each element by the mass or by the molar mass?
