Physics 541: Homework Questions Due February 1st

**1**- If we say that a difference of 5 magnitudes is equal to a factor of
100 in brightness of two stars, why can't we define the magnitude scale by the
following equation:
100 x (m1-m2)/5 = B2/B1? (After all, if m1=6 and m2=1, B2/B1=100).
**2**- problem 3.7
**3**- problem 3.9
**4**- problem 3.10
**5**- problem 3.11
**6**- problem 3.12
