[b]Question 3
Using data provided in question 2, by what factor do the following stars differ in observed brightness:
i) Vega vs. Deneb: a) 1, b) 10, c) 6, d) about 2.5 ?
ii) Vega vs. Polaris a) about 6.3, b) about 2, c) about 5 ?
vega: apparent magnitude = 0.03
deneb: apparent magnitude = 1.25
diff = 1.22, so factor diff = pogson's ratio = 2.5 --> d
polaris: apparent magnitude = 1.97
diff = 1.93, so factor diff = pogson's ratio x 2 = 5 --> c -
