Now, draw rays from the edge of the image back to the edges of iris and continue them until they reach the lens, then show them refracting and trace them back to the edge of the object. WebLight Reflection and Refraction 17. A doctor has prescribed a corrective lens of power +1.5 D. Find the focal length of the lens. Is the prescribed lens diverging or converging? Answer-Power of lens (P) = 1/f P = 1.5D f = 1/1.5 = 10/15 = 0.66 m A convex lens has a positive focal length. Therefore, it is a convex lens or a converging lens.

WebSilver Coating will reflect the light rays and will not allow the light rays to pass through the Convex lens to Converge. In this case the convex lens acts as if a Convex mirror. It diverges the light rays. The Focus point is on the another side of optical center. Image distance is the tricky one.

WebReflection and Refraction Quick Check. 1. What does the image of an object look like through a convex lens when the object is further from the lens than the focal point? Answer: It is upside down and smaller than the object 2. What happens when light rays. A convex meniscus lens is made of glass with refractive index, n= 1.5. WebIn terms of definitions, the Refractive Index of a lens is the ratio of the speed of light in a vacuum divided by the speed of light in the lens material. In the case of CR-39 plastics, the Refractive Index is 1.49 , meaning that light travels at almost half the speed through it than it does through a vacuum.
