Can you use this information to derive the equation ( 1 )
My doctor want to know how we get this equation
Transcribed Image Text:• Absolute Magnitude
d=10 pc
Sun
The absolute magnitude is determined
that all Stars in a 10 pc distance from the Sun.
by assuming
and th relation between the absolute magnitude and
th apparent magmitude .
if d= Star distance
apparent GlitHer
L- 1 Star Glitter when it's in distance lopc.
and
then th inverse - Squane law is given
by this relation:

Let #
and
APPerant
m= the absalute mag nitude for the Star
M = th absolute magnitude for th star
th different betwen it is
m-M= - 2.5 Log()
