Question

. Diverging lens 1 (focal length f1 = −20.0 cm) is placed a
distance of d = 45.0 cm to the left of diverging lens 2 (focal
length f2 = −15.0 cm). An object is placed p1 = 25.0 cm to the left
of diverging lens 1 and has a height of h = 16.0 cm.

(a) Where is the image formed by diverging lens 1 (i.e. what
is q1)? What is this image’s height and is it upright or inverted?
Does this image become a real or virtual object for diverging lens
2?

(b) Where is the final image (i.e. what is q2)? Is it real or
virtual? What is this image’s height and is it upright or inverted?

(c) On the figure below, draw a ray diagram of this situation.

Answer #1

A converging lens of focal length f1 = +22.5 cm is placed at a
distance d = 60.0 cm to the left of a diverging lens of focal
length f2 = −30.0 cm. An object is placed on the common optical
axis of the two lenses with its base 45.0 cm to the left of the
converging lens. (The thin-lens approximation may be assumed to
hold.) (a) Calculate the location of the final image and its
overall magnification with respect...

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?

A 3.0-cm-tall object is placed 45.0 cm from a diverging lens
having a focal length of magnitude 20.0 cm.
a) What is the distance between the image and the lens?
b) Is the image real or virtual?
c) What is the height of the image?

A converging lens with a focal length of +30 cm is placed 40 cm
to the left of a diverging lens with a focal length of -40 cm. An
object is placed 60 cm to the left of the converging lens. What is
the location and orientation of the image produced by the
combination of lenses?
Why is the answer B?
(a) Upright, on the right of the diverging lens and larger than
the main object
(b) Inverted, on the...

A diverging lens has radius of focal length f = –10.0
cm. An object is placed a certain distance dO from the mirror along
its principal axis.
For each value of dO in the table, fill in (i) the
distance dI from the lens to the image; (ii) the lateral
magnification m of the image; (iii) whether the image is real or
virtual; (iv) whether the image is on the same side of the lens as
the object or the...

A 1.8 cm tall object is placed 5 cm to the left of a converging
lens (lens #1) with a focal length of 1.3 cm. To the right of this
converging lens is a diverging lens (lens #2) that has a focal
length of 2.6 cm. The diverging lens is placed 22.4 cm from the
converging lens. Where is the final image, is it real or virtual,
and is it upright or inverted?

Two thin lenses with a focal length of magnitude 10.0 cm , the
first diverging and the second converging, are located 7.50 cm
apart. An object 3.00 mm tall is placed 16.7 cm to the left of the
first (diverging) lens.
How far from this first lens is the final image formed?
Is the final image real or virtual?
What is the height of the final image?
Is it upright or inverted?
Thank you!!

Two thin lenses with a focal length of magnitude 11.5 cm, the
first diverging and the second converging, are located 8.62 cm
apart. An object 1.90 mm tall is placed 19.2 cm to the left of the
first (diverging) lens.
A. How far from the first lens is the final image formed?
B. Is the final image virtual or real?
C. What is the height of the final image?
D. Is it upright or inverted?

Two thin lenses with a focal length of magnitude 11.0 cm, the
first diverging and the second converging, are located 8.25 cm
apart. An object 1.60 mm tall is placed 18.3 cm to the left of the
first (diverging) lens. Part A How far from this
first lens is the final image formed? Part B Is
the final image real or virtual? Part C What is
the height of the final image? Part D Is it
upright or inverted?

Consider a converging lens whose focal length is 5.47 cm. An
object is placed on the axis of the lens at a distance of 11.7 cm
from the lens.
1. How far is the object's image from the lens? In
centimeters.
2. If it can be determined, is the image real or virtual?
virtual
real
cannot be determined
3. If it can be determined, is the image upright or inverted
with respect to the object?
inverted
upright
cannot be determined
