- 4. An object is 2 meters from a thin lens with a focal length of 50 cm. Apply the thin-lens equation to calculate the image distance from the lens and magnification.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 enlarged1. Consider a cuboid made of crown glass which has inner space filled with water. A ray of light is incident onto the 10 cm thick block of glass on the top face of the cuboid at 60◦ from the normal. It then meets the glass-water boundary and is refracted again and continues through a water thickness of 5 cm before reaching another water-glass boundary. The ray of light is again refracted and continues in the 10 cm thick block of glass on the base of the cuboid and eventually exits into air. (a) Draw a clearly labelled diagram of the path the ray of light takes. (b) Calculate all the angles of refraction and incidence at each boundary. (c) Calculate the optical path of the ray of light from the point it is incident on the surface of the cuboid to the point it exits into air on the other end.
- Create 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.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?
