... Problem 6) The Keck Telescopes: The two Keck Telescopes are each hexagonal, 10 meters in diameter, and have 17.5 meter focal length. Because they have hexagonal primary mirrors, we need to be careful how we define the mirror "diameter". So let's simplify by approximating the hexagons by circular mir ...
