Chapter 1--THE UNIVERSE




Solutions to Numerical Exercies


Key Concepts:

  • Universality of Physical Laws--same stuff is going on
  • All the stuff in Problem#1--Atomic Spectra, etc.
  • Measuring Distance-- Light Year


    Demo:

    Looking at light from a single element (Neon or Hydrogen or......) with a diffraction grating. Results: Light is spread out into a rainbow of fruit flavors, but only certain, SPECIFIC flavors are there. This was an example of an emission spectra, what would an absorption spectra look like for the same elements?


    Look and see what's out there.
