A converging lens with a focal length of and a diverging lens with a focal length of are apart. A tall object is in front of the converging lens.

a. Use ray tracing to find the position and height of the image. Do this accurately using a ruler or paper with a grid, then make measurements on your diagram.

b. Calculate the image position and height. Compare with your ray-tracing answers in part a.

a. The ray tracing to find the position and height of the image is given below.

b. The position of the image is away from the first lens.
