Question

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?

Answer #1

An object is placed 78.1 cm in front of a diverging lens with a
focal length of magnitude 37.3 cm. A converging lens having a focal
length of magnitude 27.49 cm is placed 105.3 cm past the first
lens. Where is the final image formed. Is this image Real or
Virtual. Inverted or Non-Inverted? Also calculate the
magnification.

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 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...

An object is placed 100 cm in front of a diverging lens of focal
length -25 cm. A converging lens with a focal length of magnitude
32.7 cm is placed 30 cm past the first lens. What is the lateral
magnification of this system of lenses?

An object is 17.5 cm to the left of a lens of focal length 8.5
cm. A second lens of focal length -30 cm is 5 cm to the right of
the first lens.
Find the distance between the object and final image formed by
the second lens.
What is the overall magnification?
Is the final image real or virtual? Upright or inverted?
