Question

Two lenses are placed along the *x* axis, with a
diverging lens of focal length −8.70 cm on the left and a
converging lens of focal length 17.0 cm on the right. When an
object is placed 14.0 cm to the left of the diverging lens, what
should the separation *s* of the two lenses be if the final
image is to be focused at * x* = ∞?

Answer #1

Two lenses are placed along the x axis, with a diverging lens of
focal length −7.40 cm on the left and a converging lens of focal
length 15.0 cm on the right. When an object is placed 14.0 cm to
the left of the diverging lens, what should the separation s of the
two lenses be if the final image is to be focused at x = ∞?

Two converging lenses are placed 40.0 cm apart. The focal length
of the lens on the right is 21.0 cm , and the focal length of the
lens on the left is 10.5 cm . An object is placed to the left of
the 10.5 cm focal-length lens. A final image from both lenses is
inverted and located halfway between the two lenses.
How far to the left of the 10.5 cmcm focal-length lens is the
original object?

A diverging lens with a focal length of -11.3 cm and a
converging lens with a focal length of 14.6 cm have a common
central axis. Their separation is 30.9 cm. An object of height 1.0
cm is 33.1 cm in front of the diverging lens, on the common central
axis. Find the location of the final image produced by the
combination of the two lenses.
Where is the image located as measured from the converging
lens?

object is placed 31 cm to the left of the converging lens.
A.Where will the image be if the diverging lens is 39 cm
from the converging lens?
Express your answer using two significant figures. di = ? cm
from the diverging lens

A diverging lens with a focal length of -19.7 cm and a
converging lens with a focal length of 11.0 cm have a
common central axis. Their separation is 39.5 cm. An
object of height 1.1 cm is 26.4 cm in front of
the diverging lens, on the common central axis. Find the location
of the final image produced by the combination of the two
lenses.
