He would like a prescription for contact lenses. What is the correct contact lens prescription if he normally wears his eyeglasses a distance of 2.1 cm from his eyes? dioptersCreate a ray diagram for eyeglasses that contain a diverging lens. Assume you are looking at a 2 cm tall object that is 4 cm from the lens. The focal length is 3 cm. What type of vision are they used to correct? Give both names. How do they do this? Explain.* 32. Use ray diagrams to locate the images of the following objects: (a) an object that is 10 cm from a convex lens of +15-cm focal length and (b) an object that is 10 cm from a concave lens of -15-cm focal length. (c) Calculate the image locations for parts (a) and (b) using the thin lens equation. Check for consistency.
- 3. Two converging lenses above are placed 20.0 cm apart, both with focal lengths of 10.0 cm. A candle is 30 cm away from the first lens. By means of a neat ray tracing, locate the final image formed by the combination of the two lenses. b) Use mathematics to fully describe the image created by the lenses.6. A 2.0 cm tall object is 15 cm in front of a converging lens that has a 20 cm focallength.(a) Use ray tracing to find the position and height of the image. To do this accurately, use a ruler or a paper with a grid. Determine the image distance and imageheight by making measurements on your diagram.(b) Calculate the image position and height.
