Answer:
Large binocular telescope, Keck 1 telescope, Hobby-Ebberly telescope, Subaru telescope, Gemini North telescope, Magellan 2 telescope
Explanation:
How much light a telescope can collect depends on its diameter, since in a bigger area more photons will be collected.
Remember that in a circle the area is defined as:
(1)
Where A is the area and r is its radius.
However, the radius can be determined by means of its diameter.
(1)
Where d is its diameter.
An example of this is when a person is collecting raindrops with a bucket and with a cup. Since the bucket has a bigger area than the cup, it will collect more raindrops by unit of time. In this scenario the raindrops represent the photons.
To determine the light collecting area of each telescope, equation 2 will be replaced in equation 1.
(3)
