Keck-I has a 10m diameter mirror. HST (Hubble Space Telescope) has a 2.4m mirror.
What is the ratio of the light gathering power of Keck-I to the light-gathering power of HST?
[Compute the ratio (light gathering power of Keck)/(light gathering power of HST) and express as a decimal. Do not use scientific notation when entering your answer. ]
[Hint: model the telescope mirrors as circular disks with the indicated diameters. What property of the telescope mirror shape determines how much light it collects?]
The question is number 5 and this is all the information I have.
In the dark, your pupil (the aperture of your eye) expands
to a diameter of 7 mm.
How many times more light can be gathered by a
telescope with a 5.5 m diameter than by a fully dark-
adapted eye?
Increase in light gathered = I times
A small light source located 1 mm in front of a 1-m2m2 opening illuminates a wall behind. If the wall is 1 mm behind the opening (2 mm from the light source), the illuminated area covers 4 m2m2. How many square meters are illuminated if the wall is 3 mm from the light source? 5 mm? 10 mm?
