How much greater is the light-collecting area of a 6-meter telescope than a 3-meter telescope? how much greater is the light-collecting area of a 6- telescope than a 3- telescope?
a) two times
b) four times
c) six times

B) four times

Explanation:

Area of 6 meter telescope

Area of 3 meter telescope

Dividing the equations we get

Hence, the 6-meter telescope has 4 times the light-collecting area of the 3-meter telescope.

small = small current large mag large current

it doesn't. it was imagined up in the middle ages.
