An object is located 21.0 cm to the left of a diverging lens having a focal length f = -34.0 cm. (a) Determine the location of the image. cm distance location: -Select--- (b) Determine the magnification of the image. (c) Construct a ray diagram for this arrangement. Choose File No file chosen

A point source of light is placed a distance of 3f from a converging lens, where f is the focal lengthof the lens. Does this make a real or virtual image?a) real imageb) virtual imagec) no image is producedd) need more information to tell

Ch. 35

Which of the following changes would increase the focal length of a lens? O increase index of refraction of lens material. O increase radius of curvature of surface. O decrease radius of curvature of surface. use red colored lens material.

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.
