So the image distance is positive here. you can easily verify that the focal length is in the positive x direction for a convex lens while it is along the … WebThe focal length f of a diverging lens is negative. An expanded view of the path taken by ray 1 shows the perpendiculars and the angles of incidence and refraction at both surfaces. Figure 3 shows a concave lens and the effect it has on rays of light that enter it parallel to its axis (the path taken by ray 2 in the Figure is the axis of the lens). 2 3 二羟基苯甲酸WebThese equations, called the thin-lens equation and the lens maker’s equation, allow us to quantitatively analyze thin lenses. Consider the thick bi-convex lens shown in Figure 2.24. The index of refraction of the surrounding medium is n 1 (if the lens is in air, then n 1 = 1.00) and that of the lens is n 2. 2 3 和 2 3

"WebIf the image and object are on the same side of the lens, the image distance is negative and the image is virtual. For converging mirrors, the focal length is positive. Similarly, a converging lens always has a positive f, and a diverging lens has a negative f. The signs associated with magnification also work the same way for lenses and mirrors.
