Description
Astronomy – Tutorial #2.  Lyman series  electrons do emission and absorption - - + n=2 n=1   Balmer series  only absorbs  n=2  n=3  what % is absorbed  determines whether weak or strong  depending on the atmosphere and temperature  hot stars  Paschen  medium heat stars  Balmer  Paschen and Balmer  strong  the hotter stars are  increase in distance between electrons and nucleus  plasma  no electrons around atom  too hot  excited  max energy amount of energy that can be emitted from a Hydrogen atom  = Joules  ionization energy  calculating energy from(wavelength)  ex. energy of Hydrogen atom= ⁄  Q. calculate the energy difference between n=3 and n=2  (absorbed wavelength)  A. ( ⁄ ⁄ )  Joules  ≈ Joules  energy difference  ⁄  v = c  ⁄  ⁄  = m  = m  ≈660nm  review of prefixes  nano=  micro=  milli=  centa=  kilo=  mega=  giga=  tera=  HR Diagram (page 128-130)  plot of stars’ luminosity v.s. temperature  stars are blackbodies  luminosity  intensity added up over…
