Antonio VillarrealConverging Lens Image and Object RelationshipsBackgroundIn optical terms an object is anything one is looking at through a lens or in a mirror. The image is what the lens or mirror produces (often an optical system produces an image on the retinal plane within your eye, but this is not always the case). The focal length of a lens or a mirror is a parameter commonly used to identify lenses by radius of curvature. Aconverging lens is a common type of lens having two convex surfaces.Given an object and a lens or mirror of any shape or material one may determine the location of the image the lens or mirror forms from the lens/mirror based on the laws of refraction and reflection. This, however, is frequently complex and cumbersome. In the case of thin lenses or mirrors with spherical surfaces the relationship between object distance, image distance and focal length is:111oifddIBThe magnification of the image is given by: iioodhmdhObjectiveIn this lab you will empirically explore relationships between the object distance and object height to image distance and image height for a certain focal length convex lens, and look at the images formed in the convex lens.
