Practice Problem on Lenses in Combination
Two lenses are placed on the x-axis.
The first lens is a converging lens with focal length 15 cm placed at x = -5 cm.
The second lens is a converging lens with focal length 12 cm placed at x = 9 cm.
If an object is placed at x = -11 cm,
what is the position of the image, image type (virtual or real),
and magnification of the image?
ANSWER = (x = 33.00 cm, real, m = -1.67)
