A converging lens of focal length 19.2 cm is separated by 55.3 cm from a converging lens of focal length 4.72 cm. Calculate the position (relative to the second lens) of the final image of an object placed 39.9 cm in front of the first lens.
If the height of the object is 3.10 cm, what is the height of the final image (A negative height indicates an inverted image)?
If the two lenses are now placed in contact with each other and the object is 5.32 cm in front of this combination, where will the image be located?
