Optics Angular Magnification by a Simple Microscope continued The object is now moved so that the image is at infinity. Obviously, b is now a smaller angle than in the previous case.
Now, b = h/f so the angular magnification is now given by
This represents a lower magnification than when the image is at the near point because D is a negative quantity (it is a virtual image distance). |
