I believe that Lavelle said to not have the class overlap with any of your other classes just in case. Since he is teaching it, I assume that the structure will be the same for 14B!

Re: Calculating grade

the total is out of 500, so add up your midterm 1 and 2 raw scores, chem community points, and homework points so that you can see how many you have as of right now. You can also see what you need on the final to earn the grade that you want!

Re: Textbook Question 1A 15

First you determine that the final energy level is n=1, because it is UV light. Then you convert the wavelength into into meters. From there, you find the frequency, v, from the equation v=c/lambda. You then plug in n1^2, Rydberg's constant, and the frequency into the equation v=R[1/n1^2-1/n2^2]. An...

And since you need the wavelength and not frequency, v changes to c/wavelength. The final equation would be (3.00*10^8)/3.29*10^15[1/4-1/16], and then you multiply y...
