You want to create a telescope with a resolving power of 0.075 arc seconds at a wavelength of 550 nm. What diameter (in m) do you need? If you want to increase the light gathering power by a factor of 10, by what factor does the diameter need to increase? What would the new resolving power be (in arc seconds)? Part 1 The resolving power of a telescope is given by 2 a=2.06 x 105 where both and D must have the same units. We need to solve this expression for the diameter. You should express your values in meters. 10% (0.75 D = 2.06 x 105 D = m 0.075 arc seconds m You want to create a telescope with a resolving power of 0.075 arc seconds at a wavelength of 550 nm.
