Brightness of stars Stars are classified into categories of brightness called magnitudes. The faintest stars, with light flux Lo, are assigned a magnitude of 6. Brighter stars of light flux L are assigned a magnitude m by means of the formula m = 6 – 2.5 log Lo (a) Find m if L = 1004L0. (b) Solve the formula for L in terms of m and Lo.

Question
Brightness of stars Stars are classified into categories of
brightness called magnitudes. The faintest stars, with light
flux Lo, are assigned a magnitude of 6. Brighter stars of light
flux L are assigned a magnitude m by means of the
formula
m = 6 – 2.5 log
Lo
(a) Find m if L = 1004L0.
(b) Solve the formula for L in terms of m and Lo.
