L = (b) A knob adjusts the eyepiece forward and backward. Suppose the telescope is in focus with an eyepiece giving a magnification of 20.3. By what distance must the eyepiece be adjusted when the eyepiece is replaced, with a resulting magnification of 1.0 ✕ 102? Must the eyepiece be adjusted backward or forward? Assume the objective lens has a focal length of 2.32 m. (Use a positive value if the eyepiece must be moved forward toward the objective lens and negative values if the eyepiece must be moved backwards.) cmA thin plastic lens with index of refraction n = 1.69 has radii of curvature given by R, = -11.5 cm and R, = 30.0 cm.

- A particular nearsighted patient can’t see objects clearly beyond 15.0 cm from their eye. Determine (a) the lens power required to correct the patient’s vision and (b) the type of lens required (converging or diverging). Neglect the distance between the eye and the corrective lens.3) A lens has a refractive index of 1.30. In air, it is a converging lens. Will it still be a converging lens if placed under water? Explain using a ray diagram.6. A 2.0 cm tall object is 15 cm in front of a converging lens that has a 20 cm focal length. (a) Use ray tracing to find the position and height of the image. To do this accu- rately, use a ruler or a paper with a grid. Determine the image distance and image height by making measurements on your diagram. (b) Calculate the image position and height. Compare with your ray-tracing an- swers in part a.
