HW2 Bugfixes

Homework 2 has been updated (minor) - in particular, #4b was redundant and has been removed, along with a few typos.


  1. in number 1, is that supposed to be 8*(pi)*h*c instead of 8*(pi)*h*c^2?

  2. For energy density, there would be one less factor c; for intensity as stated in the problem it is OK as written. Intensity and energy density differ by a factor c/4.

    See -- their formula has a factor 4pi less because I already included the solid angle factor.
