Which lens has the greater curve in a compound microscope?
–>Great curvatures has rounder lenses produced greater magnification so they have shorter focal length. In the compound microscope the Objective lens has a smaller focal length and hence greater curvature. If you are talking about aperture(that controls the amount of light entering through the telescope) than read ahead. In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture of an optical system is the opening that determines the cone angle of a bundle of rays that come to a focus in the image plane. The aperture determines how collimated the admitted rays are, which is of great importance for the appearance at the image plane. A wide aperture results in an image that is sharp around what the lens is focusing on and blurred otherwise. The aperture also determines how many of the incoming rays are actually admitted and thus how much light reaches the image plane (the narrower the aperture, the darker the image).
