Question

One diverging and converging lenses are separated by 12cm. The first lens on the left is divergent with focal point of 25cm while the second lens on the right is f=10cm. The object is real and located 10cm in front of the divergent lens. a) Find the position of the image due to the first lens, b) Find the final position of the image, c) calculate the total magnification.

Answer #1

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...

A converging lens, which has a focal length equal to 8.4 cm, is
separated by 30.5 cm from a second lens. The second lens is a
diverging lens that has a focal length equal to -13.7 cm. An object
is 16.8 cm to the left of the first lens.
(a) Find the position of the final image using both a ray
diagram and the thin-lens equation. __________cm to the right of
the object
(b) Is the final image real or...

An object and two lenses are arranged so that the object is to
the left of and 40cm from a converging lens. The magnitude of the
focal length of the first ens is 25cm. A diverging lens is 100cm to
the right of the first lens and the magnitude of the focal length
is 15cm. Find the location of the final image relative to the
original object, the overall magnification.

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...

A converging lens and a diverging lens, separated by a distance
of 30.0 cm, are used in combination. The converging lens has a
focal length of 15.2 cm. The diverging lens is of unknown focal
length. An object is placed 19.3 cm in front of the converging
lens; the final image is virtual and is formed 12.0 cm in front of
the diverging lens. What is the focal length of 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.

An object 2.00 cm high is placed 31.1 cm to the left of a
converging lens having a focal length of 26.1 cm. A diverging lens
having a focal length of −20.0 cm is placed 110 cm to the right of
the converging lens. (Use the correct sign conventions for the
following answers.)
(a) Determine the final position and magnification of the final
image. (Give the final position as the image distance from the
second lens.)
Find
final position in...

Two converging lenses, each having a focal length equal to 10.7
cm, are separated by 38 cm. An object is 21.4 cm to the left of the
first lens.
(a) Find the position of the final image using both a ray
diagram and the thin-lens equation.
cm to the right of the object
(c) What is the overall lateral magnification?
