The following schematic diagram shows the path of light rays passing through in a light microscope. If the angular width of the cone of rays collected by the objective lens (2?) is increased, would the resolution improve (I; i.e. the resolution limit decreases) or deteriorate (D)? Write down I or D as your answer.
