Suppose you are on a planet orbiting a star 9.0 light years away. (One light year is the distance light travels in one year.) Part A At this distance, what is the minimum diameter for an objective mirror that will just barely resolve the earth and the sun? Assume a wavelength of 600 nm, the distance from the earth to the sun is 1.5×1011m.
