Question-

An object is 10 cm in front of a convergent lens that forms a real image 15 cm from the lens. The object is 2 cm high.

a) Calculate the focal length of the lens and the height of the image. Construct a ray diagram to scale that verifies your results

b) Now place a divergent lens with focal length 15 cm to the right of the image produced in part 1 above, to produce a new image that is upright with respect to the original object and is 6 cm high. Use both the lens equation and scale ray diagram to show the final result.
