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 = ∞?

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?

A diverging lens with a focal length of -13 cm is placed 12 cm
to the right of a converging lens with a focal length of 22 cm . An
object is placed 34 cm to the left of the converging lens.
Where will the final image be located?
Express your answer using two significant figures.

Where will the image be if the diverging lens is 58 cm from...

A diverging lens with a focal length of -13 cm is placed 12 cm
to the right of a converging lens with a focal length of 19 cm . An
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 -13 cmcm is placed 11
cmcm to the right of a converging lens with a focal length of 22
cmcm . An object is placed 36 cmcm to the left of the converging
lens. a) Where will the final image be located? b)Where will the
image be if the diverging lens is 55 cmcm from the converging
lens?Find the image location relative to the diverging lens.

Two identical diverging lenses are separated by 22 cm. The focal
length of each lens is -13 cm. An object is located 4.4 cm to the
left of the lens that is on the left. Determine the final image
distance relative to the lens on the right.

Two identical diverging lenses are separated by 14 cm.
The focal length of each lens is -9.5 cm. An object is located 3.9
cm to the left of the lens that is on the left. Determine the final
image distance relative to the lens on the right

Two identical diverging lenses are separated by 20 cm. The focal
length of each lens is -9.8 cm. An object is located 4.7 cm to the
left of the lens that is on the left. Determine the final image
distance relative to the lens on the right.

Two lenses, one converging with focal length 20.0 cm and one
diverging with focal length -11.7 cm , are placed 25.0 cm apart. An
object is placed 60.0 cm in front of the converging lens.
Determine the position of the final image formed.
Express your answer with the appropriate units.
di =
Determine the magnification of the final image formed.
m=

Two thin lenses with a focal length of magnitude 10.0 cm , the
first diverging and the second converging, are located 7.50 cm
apart. An object 3.00 mm tall is placed 16.7 cm to the left of the
first (diverging) lens.
How far from this first lens is the final image formed?
Is the final image real or virtual?
What is the height of the final image?
Is it upright or inverted?
Thank you!!
