Suppose that you wish to construct a telescope that can resolve features 7.0km across on the moon.383, 000 km away. You have a 2.0-m-focal-length objective lens whose diameter is 11.0cm. what focal –length eyepiece is needed if your eye can resolution objects 0.10mm apart at a distance of 25cm? What is the resolution limit (radians) set by the size of the objective lens (that is bi diffraction)? Use λ= 550nm. |
