# An object is placed 5 cm from a diverging lens with a focal

Last updated: 7/5/2022

An object is placed 5 cm from a diverging lens with a focal length of 3 cm. a) [1.5 points] Complete the ray diagram below to determine the location of the image using at least two principal rays. Summarize the characteristics of the image (real/virtual, upright/inverted, larger/smaller/same size) from your diagram. Explain what these characteristics tell us about the signs of the image distance (d;) and image height (h₁). b) Calculate the height of the image (hi) and its distance from the center of the lens (di). Show your work and note whether your results are consistent with your diagram above. c) What is the magnification of the image (both sign and value)? How does the magnification tell you about the characteristics of the image? Show your work and explain. d) How could you move the object such that the magnification is -2/3, rather than the value you calculated above? If this is not possible, state so explicitly. Explain.
