Question

Problem 2 a. Using the telescope on-board his spaceship, Captain Kirk barely manages to resolve two distant galaxies that are 0.3 arc-seconds apart (1 arc-second 1/3600 Degree). If he is imaging at 550 nm wavelength, what is the effective aperture (diameter) of the objective lens of the telescope? Assume that there are no geometrical aberrations. (5 points) b. Consider the following imaging setup with a transverse magnification Iml3, If we are to resolve the image of the two fixed point sources separated by a distance of d 600 nm, what should the minimum angle θ be? Use small angle approximation, such that θ-sin θ, and assume that the imaging wavelength is 370 nm. (5 points) Convex)
