Question

A converging lens with a focal length of 20 cm and a diverging lens with a focal length of -34 cm are 74.0 cm apart. A 2.6-cm-tall object is 40 cm in front of the converging lens.

1. Calculate the distance between image and diverging lens.

2. Calculate the image height.

Answer #1

A converging lens with a focal length of 60 cm and a diverging
lens with a focal length of -70 cm are 310 cm apart. A 2.7-cm-tall
object is 80 cm in front of the converging lens.
Calculate the distance between the final image and the diverging
lens.
Express your answer to two significant figures and include the
appropriate units.
Calculate the image height.

A converging lens with focal length of 30 cm and a diverging
lens with focal length of 10 cm are 15 cm apart. A 4-cm-tall object
is 10 cm in front of the 30-cm-focal-length lens. Use ray tracing
to find the height of the image in cm

A diverging lens with a focal length of -11.3 cm and a
converging lens with a focal length of 14.6 cm have a common
central axis. Their separation is 30.9 cm. An object of height 1.0
cm is 33.1 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 15-cm-focal-length converging lens is 20 cm to the right of an
8.0-cm-focal-length converging lens. A 2.9-cm-tall object is
distance L to the left of the first lens.
Part A) For what value of L is the final image of this two-lens
system halfway between the two lenses?
Part B) What is the height of the final 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?
What is the...

A diverging lens with a focal length of -15 cm and a converging
lens with a focal length of 15 cm have a common central axis. Their
separation is 12 cm. An object of height 1.0 cm is 10 cm in front
of the diverging lens, on the common central axis.
(a) Where does the lens combination produce the final image of
the object (the one produced by the second, converging lens)?
in cm
(b) What is the height of...

Two converging lenses with focal lengths of 40 cm and 19 cm are
10 cm apart. A 3.2 cm tall object is 15 cm in front of the 40 cm
focal-length lens. Calculate the distance between the final image
and the 19 cm focal-length lens and the final image height.

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?

An object i 5 cm in front of diverging lens (focal length 10
cm). 20 cm behind diverging lens is converging lens (focal length
20 cm). where is the image? is it real or virtual?
