Question

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 virtual?

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!!

first (diverging) lens.
A. How far from the first lens is the final image formed?
B. Is the final image virtual or real?
C. What is the height of the final image?
D. Is it upright or inverted?

An
object is placed 5cm in front of a diverging lens of focal length
25 cm. A second converging lens of focal length 15cm is positioned
20 cm to the right of the first lens. What is the final image
distance? What is the magnification of the final image? Is it
upright of inverted? Real or virtual?

Two converging lenses, each of focal length 15.1 cm, are placed
40.4 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 ______ cm ---Location---a) in
front of the second lens. b) behind the second lens. c)in front of
the first lens.
What is the magnification of the system?
M = ______ ?

Two thin lenses with a focal length of magnitude 11.0 cm, the
first diverging and the second converging, are located 8.25 cm
apart. An object 1.60 mm tall is placed 18.3 cm to the left of the
first (diverging) lens. Part A How far from this
first lens is the final image formed? Part B Is
the final image real or virtual? Part C What is
the height of the final image? Part D Is it
upright or inverted?

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
the second lens.
What is the distance?
What is the magnification of the system?

A converging lens with a focal length of 4.8 cm is
located 24.8 cm to the left of a diverging lens having a
focal length of -15.0 cm. If an object is located 9.8
cm to the left of the converging lens, locate and describe
completely the final image formed by the diverging lens.
Where is the image located as measured from the diverging
lens?
What is the magnification?
Also determine, with respect to the original object whether the
image...

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.
Where is the image located as measured from the converging
lens?

A) An object is placed 26 cm in front of a converging lens of
focal length 5 cm. Another converging lens of focal length 10 cm is
placed 20 cm behind the first lens.
1) Find the position of the final image with respect to the second
lens. ____cm
2) Find the magnification of the final image. _____
B) A diverging lens of focal length −12cm projects the image of
an object onto a wall. What is the object distance if...

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?
