Problem concerning zoom lens in camera...
This problem deals with a diverging lens placed to the right of a converging lens. The converging lens has a focal length of 12cm and the diverging lens has a focal length of -12cm. The lenses are separated by 4cm.
a) For a distant object, where is the image of the
converging lens?
b) The image of the converging lens serves as the object
for the the diverging lens. What is the object distance
for the diverging lens?
c) Where is the final image?
d) Repeat for a lens separation of 8 cm.
I'm really confused by this question, it seems to me like the wording is off but I might be misinterpreting it :S Thanks for any help! :)
