• Either you can take the ratio of the areas
found from using the slider tool, or you can
use the concept that the area goes as the
diameter squared. Both methods give an
answer of the larger telescope collecting 4
times more light.
• Method 1: area of 2-m telescope / area of 1-
meter telescope = 3.14/0.79 = 4
• Method 2: ratio of areas is the square of the
ratio of diameters: (2/1)² = = 4
