Knowing the advantages and disadvantages of each lens type is crucial when choosing between optics as each has its own purpose. Understanding optical lens geometries helps anyone, from novice to expert, geometrical optics is usually simpler. The statements below about lenses are accurate for thin lenses, i.e., those having a thickness at the center that is small compared to the distance between the lens and the image or object. The lenses in this experiment can be considered thin. There are two types 2 Geometric Optics Figure 1: Types of lenses and mirrors Consider re°ection from a concave spherical mirror, as shown in Figure 2. This mirror is a portion of a sphere of radius R whose center is at C. R is the radius of curvature and is the distance C from the mirror.

The lenses in this experiment can be considered thin. There are two types Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays.The ray in geometric optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances. Geometric Optics Light from this page or screen is formed into an image by the lens of your eye, much as the lens of the camera that made this photograph. Mirrors, like lenses, can also form images that in turn are captured by your eye.

Section Overview: The action of a simple lens, similar to many of those used in the microscope, is governed by the principles of refraction and reflection and can be understood with the aid of a few simple rules about the geometry involved in tracing light rays through the lens. The basic concepts explored in this discussion, which are derived from the science of Geometrical Optics, will lead to an understanding of the magnification process, the properties of real and virtual images, and
