Question

An object 5.1 mm high is on the optical axis of two lenses with
focal lengths *f*_{1} = +5.0 cm,
*f*_{2} = +10 cm. The object is 6.7 cm to the left
of the first lens, and the second lens is 32 cm to the right of the
first lens. Find the position (relative to the second lens) and the
size of the final image by calculation.

Answer #1

An object 4.3 mm high is on the optical axis of two lenses with
focal lengths f1 = +5.0 cm, f2 = +10 cm. The object is 6.4 cm to
the left of the first lens, and the second lens is 31 cm to the
right of the first lens. Find the position (relative to the second
lens) and the size of the final image by calculation.

An object 5.2 mm high is on the optical axis of two lenses with
focal lengths f1 = +5.0 cm,
f2 = +10 cm. The object is 6.3 cm to the left
of the first lens, and the second lens is 32 cm to the right of the
first lens.

Two converging lenses having focal lengths of f1 = 11 cm and f2
= 19 cm are placed 50 cm apart as shown in Figure. The final
inverted image is to be located between the lenses at the position
38 cm to the right of the first lens. How far (in cm) to the left
of the first lens should the object be positioned? Express the
answer (numerical value only) with one decimal place.

Part 1
Two thin converging lenses of focal lengths f1 = 9.6 cm and f2 =
12 cm are separated by a = 20 cm, as in the figure below. An object
is placed p1 = 15 cm to the left of the first lens. Find the
position of the final image from the second lens. Answer in units
of cm.
Part 2
What is the magnification of the second lens?
Part 3
Calculate the magnification of the whole system.

Two converging lenses, the first with focal length f1 = 25 cm
and the second with focal length f2 = 15 cm are separated by a
distance of ` = 65 cm. An object is place at a distance of do1 = 45
cm to the left of the first lens.
(a) What will be the distance from the second lens that the final
image is produced? Is this image to the left or right of the second
lens? Justify...

Two converging lenses having focal lengths of f1 = 11.4 cm and
f2 = 20.0 cm are placed d = 50.0 cm apart, as shown in the figure
below. The final image is to be located between the lenses, at the
position x = 32.7 cm indicated. On the left, an arrow originating
from a long horizontal line points upward and is labeled "Object."
A vertical, convex lens, labeled "f1," is centered upon the
horizontal line and is positioned a...

An optical technician mounts two thin lenses along a single
optical axis (the lenses are at right angles to the line connecting
them, and they appear concentric when viewed from either end). The
lenses are identical, each with a positive (converging) focal
length of +15.2 cm. They are separated by a distance of 40.4 cm.
Lens 1 is to the left of Lens 2.
In order to evaluate the lens combination as a single optical
instrument, the technician places an...

An object 8 cm high is placed 12 cm to the left
of a converging lens of focal length 8 cm. A
second converging lens of focal length 6 cm is
placed 36 cm to the right of the first lens. Both
lenses have the same optical axis. Find the position, size and
orientation of the image produced by the two lenses in combination.
Confirm the validity of your result by drawing a ray-tracing
diagram.
