An electron ps from the 6th to te 3rd energy level in the hydrogen atom:
a) calculate the wavelength
b) calculate the frequency
c) calculate te enrgy
d) into which spectral series would the photon be grouped?
(i really just need to formulas, then i could solve myself...)

1/wavelength = R(1/3^2  1/6^2)
R = Rydberg constant.
b) c = wavelength*frequency
c) E = h*frequency
d) You can answer this after you know the wavelength.
