Answer:
flux ratio is 100
so correct option is C) 100.0
Explanation:
given data
magnitude difference = 5
to find out
flux ratio
solution
we know that magnitude difference ( m1 -m2) is calculate as
magnitude difference = [tex]k log\frac{f1}{f2}[/tex] ...........1
here f1 and f2 are flux ratio
and we know k = -2.5 is a constant
so put here value we get
5 = -2.5 [tex]log\frac{f1}{f2}[/tex]
2 = - log F
so flux ratio is 100
so correct option is C) 100.0
