Question

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?

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 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 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)...

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 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.

1) Two convex lenses, both with focal length 1.5 m, are placed
such that the light from a 4 cm tall object passes through each.
The object is placed 4.5 m from the first lens, and the lenses are
3 m apart. Where will the image from the first lens be? Will it be
real or virtual? Will it be upright or inverted? Where will the
final image be (using both lenses)? Will it be real or virtual?
Upright or...

The focal lengths of the converging and diverging lenses are +15
and -20 cm, respectively. The distance between them is 50 cm and
the object is placed 10 cm to the left of the converging lens.
Determine the location of the final image with respect to the
diverging lens. Is this image real or virtual? Find the total
magnification; is the image inverse or upright?

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?

. Diverging lens 1 (focal length f1 = −20.0 cm) is placed a
distance of d = 45.0 cm to the left of diverging lens 2 (focal
length f2 = −15.0 cm). An object is placed p1 = 25.0 cm to the left
of diverging lens 1 and has a height of h = 16.0 cm.
(a) Where is the image formed by diverging lens 1 (i.e. what
is q1)? What is this image’s height and is it upright or...

Two lenses, one converging with focal length 21.0 cm and one
diverging with focal length − 12.0 cm , are placed 25.0 cm apart.
An object is placed 60.0 cm in front of the converging lens.
