I had my exam this morning, and it went quite well! I studied for 5 hours last night, and thanks to your help too, I find the unit was easier.
My diploma (final) exam is coming up in a few weeks after Christmas break; so I may pop in if I have any more questions from previous units as I study...
The only part I could find energy for was the photon, by using E = hc/(wavelength)
The nucleus has no kinetic energy, how would I find it's potential? Or does it have none?
I am not sure how to find the energy of the electron either, since I only know the charge to be 1.6 x 10^-19. Is that...
[SOLVED] Value of inifinity?
Edit: typo in title (infinity); sorry
Homework Statement
What is the shortest wavelength of light emitted by an electron in the Brackett series of spectra lines of the hydrogen atom?
Homework Equations
1 / (wavelength) = RH ( (1/nu^2) - (1/nl^2) )...
Thank you so much!
I believe that I have figured out number one.
I found the energy of each wavelength to be:
4.97 x 10^-19 J
3.62 x 10^-19 J
3.49 x 10^-19 J
and 2.93 x 10^-19 J
Then I found the energy of the electron (2.00 eV multiplyed by 1.6x10^-19, which equals 3.2x10^-19)...
If you can help me on even one of these questions, it's greatly appreciated!
