Basic lens formula 1/f= 1/u+1/v where f= focal length, v=image dist from lens and u= object distance from lens.
The formula is magnification M=v/u . So obviously as the object gets closer to the focus of the (convex) lens, the image and magnification gets larger. Same equation applies when the object distance is less than the focal length, only the 'virtual' image and the object are on the same side of the lens-this is the principle of the simple microscope or magnifying glass.

magnification = length of sketch divided by actual size of image.
are you revising for AS bio 2??
