The Webb space telescope, scheduled to be launched in 2010, will have a mirror 6 m in diameter. Compared with the Hubble space telescope, whose mirror has a 2.4 m diameter, it will be able to resolve objects whose angular separation is about
(a) 2.5 times smaller;
(b) 5 times smaller;
(c) an order of magnitude smaller;
(d) the same: the larger mirror only increases the amount of light gathered.
