Question

A real, upright object of 3.50 cm in height is placed to the
left of a *converging* lens with focal length 12.0 cm. A
*diverging* lens with focal length 6.00 cm is located 20.0
cm *to the right of the converging lens*.

**Read carefully**: The *final* image formed
by the two lens system is 5.00 cm to the *right* of the
converging lens.

- Draw a simple yet clear diagram of the setup, labeling lenses, object distances, and images distances as appropriate as you work through parts (b), (c), and (d).
- Determine the position of the original object (with respect to the converging lens).
- Is the final image inverted or upright relative to the original object?

Is the final image real or virtual?

Answer #1

A 1.8 cm tall object is placed 5 cm to the left of a converging
lens (lens #1) with a focal length of 1.3 cm. To the right of this
converging lens is a diverging lens (lens #2) that has a focal
length of 2.6 cm. The diverging lens is placed 22.4 cm from the
converging lens. Where is the final image, is it real or virtual,
and 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?

An object which is 1.23 cm high is placed 10.00 cm to the left
of a lens. It is not known if the lens is converging or diverging.
An image forms 3.20 cm to the left of the lens. (a) Determine if
the lens is converging or diverging by calculating the focal length
of the lens. (b) Calculate the height of the image. (c) Describe
the image. Is it real or virtual, upright or inverted and enlarged
or diminished?

An object of height 6.00 cm is placed 24.0 cm to the left of a
converging lens with a focal length of 10.5 cm. Determine the image
location in cm, the magnification, and the image height in cm.
(a) the image location in cm
(b) the magnification
(c) the image height in cm
(d) Is the image real or virtual?
(e) Is the image upright or inverted?

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...

An
object is placed 30 cm to the left of a converging lens of focal
length 10 cm. A diverging lens of focal length -15 cm is 20 cm to
the right of the converging lens.
a) Where is the image created by the first lens relative to
the first lens?
b) Is it real or virtual?
c) Where is the final image relative to the second lens?
d) Is it real or virtual?
e) What is the final lateral...

A converging lens with a focal length of +30 cm is placed 40 cm
to the left of a diverging lens with a focal length of -40 cm. An
object is placed 60 cm to the left of the converging lens. What is
the location and orientation of the image produced by the
combination of lenses?
Why is the answer B?
(a) Upright, on the right of the diverging lens and larger than
the main object
(b) Inverted, on the...

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 thin lenses with a focal length of magnitude 11.5 cm, the
first diverging and the second converging, are located 8.62 cm
apart. An object 1.90 mm tall is placed 19.2 cm to the left of the
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?
