A ray diagram for the image formation of a plane mirror. It forms a virtual, upright, and unmagnified image. Convex and Concave Mirrors The relationship between the image distance, object distance, and focal length in spherical mirrors is given by the mirror equation, 1do+1di=1f, where do...
In the image below, the converging lens' focal length is 14.3 cm, d = 12.2 cm, and the diverging lens' focal length is -10.7 cm.A convex lens with a focal length of 20 cm is placed in front of a convex mirror with a focal length of 7.5 cm. A luminous object ...

This is somewhat of an artifact of the fact that most photogrammetric systems were focused at infinity. If we take the lens equation for a thin convex lens: 1f=1o+1c We can see how these values are related. As o approaches infinity, 1o approaches zero, which makes the focal length ...
What is the focal length of a makeup mirror that produces a magnification of 1.5 when a person's face is 12\ \mathrm{cm} away? Draw the ray diagram. Consider a makeup mirror that produces a magnification of 1.7 when a person's face i...
refraction. As a result, these rays converge to a focal point located at a specific distance from the lens. The focal length of the lens determines the degree of convergence. The closer an object is to the lens, the farther away the image is projected. (SeeImage.Photograph: Convex Lens....
