Question

Two
lenses are .78m apart and used to form an image. Lens 1 is
converging and has a focal lens of -.42m. lens 2 is diverging and
has a focal point og -0.35m. the object is 2.40m to the left of
lens 1. what is the distance to the final image?

Answer #1

Two converging lenses are placed 15 cm
apart. The lens A (on the left) has a focal length of 5 cm, and
lens B (on the right) has a focal length of 4 cm. An object is
placed 8 cm to the left of lens A. Draw the scenario and confirm
your findings using the equations to find:
a) the final
image distance
b) the
magnification
c) is the
image real or virtual?

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?

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...

Consider a two-lens system consisting of a diverging lens
(f=-27.0 cm) and a converging lens (f=22.0 cm). An object is placed
7.0 cm to the left of the converging lens and a final image is
produced by the two-lens system that is 20.0 cm to the left of the
diverging lens. If the converging lens is to the left of the
diverging lens, how far apart are the two lenses?

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 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.

Two lenses are placed along the x axis, with a
diverging lens of focal length −8.70 cm on the left and a
converging lens of focal length 17.0 cm on the right. When an
object is placed 14.0 cm to the left of the diverging lens, what
should the separation s of the two lenses be if the final
image is to be focused at x = ∞?

Two lenses are placed along the x axis, with a diverging lens of
focal length −7.40 cm on the left and a converging lens of focal
length 15.0 cm on the right. When an object is placed 14.0 cm to
the left of the diverging lens, what should the separation s of the
two lenses be if the final image is to be focused at x = ∞?

two things lenses of focal lengths -15cm and +15cm are
placed 12cm apart. The negative lens is positioned to the left of
the positive lens. A 4mm tall object is placed 5cm to the left of
the negative lens .calculate a) distance between object and final
image created by both lenses
b) height of the final image

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.
