Question

what could error be due to in the thin lenses experiment using a
combination of converging lens?

Answer #1

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...

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.

If a system of two thin lenses, one is a converging lense L1
with focal distance of f and the other is a diverging lens L2 with
focal distance of -5f/8. They are separated by a distance of
f/2
The question is to find the principal planes of the system by
ray tracing and calculations and the equivalent focal length. My
question is what is the meaning of equivalent focal length ,
represents what distance?I know what is the focal...

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?

When two lenses are used in combination, the first one forms an
image that then serves as the object for the second lens. The
magnification of the combination is the ratio of the height of the
final image to the height of the object. A 1.60-cmcm-tall object is
56.0 cm to the left of a converging lens of focal length 40.0 cm. A
second converging lens, this one having a focal length of 60.0 cm,
is located 300 cm to...

An optical system consists of two lenses separated by 35 cm –
first is converging with focal length 10 cm and the second is
diverging with focal length 15 cm. An object is 20 cm to the left
of the first lens. Find the position of the final image using both
a ray diagram and the thin-lens equation. Is the image real or
virtual? Erect or inverted? What is the overall magnification of
the image?

When two lenses are used in combination, the first one forms an
image that then serves as the object for the second lens. The
magnification of the combination is the ratio of the height of the
final image to the height of the object. A 2.00 cm -tall object is
50.0 cm to the left of a converging lens of focal length 40.0 cm .
A second converging lens, this one having a focal length of 60.0 cm
, is...

Two thin lenses with a focal length of magnitude 12.0 cm, the
first diverging and second converging, are located 9.00cm apart. An
object 2.50mm tall is placed 20.0cm to the left of the first
(diverging) lens. Note that focal length of diverging lens is a
negative number while focal length of converging lens would be
positive.
a) Draw a figure showing both lenses and use principal rays to
find approximate position of the image formed by the first
lens.
b)...

1. An image of a 10 cm high LED strip is formed using two
converging lenses. The two lenses are separated by a distance of
1.5 m, and the LED strip is 1 m away from the nearest lens. The
focal length of the lens closest to the LED strip is 1 m and that
of the farther lens is 0.2 m.
a) Determine the position of the image formed by this two-lens
assembly, relative to the position of the...

An object is 15.4 cm in front of a thin converging lens that has
a focal length equal to 10.0 cm. A concave mirror that has a radius
equal to 10.0 cm is 23.8 cm in back of the lens.
(a) Find the position of the final image formed by the
mirror-lens combination.
cm from the lens, on the same side as the original object.
