The light-collecting area of the 10-meter Keck telescope is <u>4 times greater </u>than the light-collecting area of the 5-meter Hale telescope.
Why?
We can calculate the light-collecting area of a telescope by using its diameter/radius. To do that, we can use the following formula:
Now, to know how much greater is the collecting area of the 10-meter keck telescope compared to the collecting area of the 5-meter hale telescope, we need to calculate their light-collecting areas and compare them.
For the 10-meter keck telescope, we have:
For the 5-meter hale telescope, we have:
Now, comparing the areas, we have:
Hence, we have that the light-collecting area of the 10-meter keck telescope is 4 times greater than the light-collecting area of the 5-meter hale telescope.
