TITLE: What is the relation of resolution with linear and angular magnification of a convex lens?
QUESTION [0 upvotes]: 1) Linear magnification is the ratio of size of image to the size of object located at same distance. Whereas angular magnification is the ratio of Visual angle subtended by image at an aided eye to visual angle subtended by object at unaided or naked eye. which of them is related to resolution?
2) On optical devices which magnification is mentioned linear or angular?

REPLY [1 votes]: In fact linear or angular magnification has nothing to do with resolution. You can have a device with large resolutions but poor magnification. To be of use resolution is increased so that the increased magnification can be useful. Resolution is related to the aperture size as given by the formula by Farcher.
