Question

Two converging lenses, the first with focal length 10.0 cm and the second with focal length 20.0 cm, are separated by 40.0 cm. An object, 3.00 cm in height, is placed 30.0 cm in front of the first lens. What is the height of the final image?

Answer #1

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!!

Two converging lenses, each of focal length 14.9 cm, are placed
39.9 cm apart, and an object is placed 30.0 cm in front of the
first lens. Where is the final image formed?
The image is located x cm ---Location--- in front of

What is the distance?
What is the magnification of the system?

Two converging lenses, the first with focal length f1 = 25 cm
and the second with focal length f2 = 15 cm are separated by a
distance of ` = 65 cm. An object is place at a distance of do1 = 45
cm to the left of the first lens.
(a) What will be the distance from the second lens that the final
image is produced? Is this image to the left or right of the second
lens? Justify...

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.

Two lenses are placed 50 cm apart. The first lens is converging
and has a focal length of 20 cm, and the second lens is diverging
and has a focal length of 15 cm. If an object is placed 55 cm in
front of the first lens, where is the final image located? Give
your answer in relation to the second lens. What is the overall
magnification? Is the final image upright or inverted? Is the final
image real or...

Two thin lenses with a focal length of magnitude 12.0 cm, the
first diverging and second converging, are located 9.00cm apart. An
object 2.50mm tall is placed 20.0cm to the left of the first
(diverging) lens. Note that focal length of diverging lens is a
negative number while focal length of converging lens would be
positive.
a) Draw a figure showing both lenses and use principal rays to
find approximate position of the image formed by the first
lens.
b)...
