A severely near-sighted sailor on a ship is asked to be on the lookout for icebergs on the horizon. To do so, he is given a Newtonian Telescope with f(objective) = 30cm and f(eyepiece)= 5 cm (see diagram in attached file).
a. If the sailor's relaxed eye focuses objects at a distance of 1m (his far-point distance), how far apart d must the telescope lenses be for the sailor to see a clear image of an iceberg?
b. With what angular magnification does the sailor see an iceberg on the horizon?
c. Is the iceberg image real or virtual? Upright or inverted?
