A device composed of 2 convergent thin lenses is considered: / and /2. The first lens (/1) has a focal length f1 = 4 cm and the second lens (/2) has a focal length of f2 = 17.5 cm. The distance between the two lenses is 32 cm. The distance object p is 5 cm (the object is placed in front of the lens f as illustrated in the figure above). The height of the object is h= 0.05 cm. What is the transverse magnification of the system composed of the two lenses I1 and l2. Don't forget to use the negative sign if the final image is inverted.
