- w9-8 A diverging lens has a focal length of −8.00 cm. What is the nature of the image formed when the object is placed at a distance of 24.2 cm from the lens? a. virtual, upright, and diminished b. real, inverted, and diminished c. virtual, upright, and enlarged d. real, inverted, and enlargedCreate 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.6. If you open your eyes underwater, you do not get a well-focused image on your retina. But if you wear goggles or a mask, you will see normally. Explain why this is the case.
- * 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.1. A patient enters an eye doctor’s office and finds the doctor tells him that his near point is 10.0 cm. The doctor also finds the patient’s far point (with eyes relaxed) is 125 cm. Each eye lens can be assumed to be 2.00 cm from the retina. a) Between what limits (units: diopters) does the power of this patient’s lens (technically lens+cornea combination) vary? b) The doctor is going to prescribe glasses. Calculate the power of the eyeglass lens the patient should use for relaxed distance vision. Is the lens converging or diverging?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.
