Two converging lenses with focal lengths of 40 cm and 20 cm are 12 cm apart. A 2.0 cm -tall object is 13 cm in front of the 40 cm -focal-length lens.

Calculate the image height. (cm)

A converging lens with a focal length of 40 cm and a diverging lens with a focal length of -40 cm are 170 cm apart. A 2.0-cm-tall object is 60 cm in front of the converging lens.

Calculate the image position. (cm)

A lens with a focal length of 25 cm is placed 40 cm in front of a lens with a focal length of 5.0 cm.

How far from the second lens is the final image of an object infinitely far from the first lens?

Is the image in front of or behind the second lens?

Two concave lenses, each with f = -11 cm, are separated by 5.4 cm. An object is placed 24 cm in front of one of the lenses.

Find the location of the final image produced by this lens combination.

in front of the lens closest to the object

beyond the lens farthest to the object

between the two lenses

Find the magnification of the final image produced by this lens combination.
