Question

When using a converging lens, how does the object’s location affect whether an image is (a) enlarged (bigger than the object) or reduced (smaller than the object) (b) upright or inverted?

Answer #1

When using a converging lens, how does the object’s
location affect whether an image is (a) enlarged (bigger than the
object) or reduced (smaller than the object) (b) upright or
inverted?

Consider how a converging lens produces a virtual image opposed
to a real image.
a. Would the virtual image be upright or inverted? Is it larger
or smaller than the object itself?
b. Can you observe this image on a screen placed in front of the
lens? Explain
c. Suppose you move the object closer to the lens. Is the image
upright or inverted? Is it larger or smaller than the object
itself?
d. If the object is closer to...

True or False
a) A converging lens can produce a virtual, upright, enlarged
image.
b) A diverging lens always produces a virtual, upright, reduced
image.
c) For a converging lens an object has to be placed between the
focal point and the lens in order to form a virtual image.
d) A converging lens can never produce a virtual, upright,
reduced image. A converging lens cannot produce a real, inverted
reduced image.
e) A diverging lens can produce a real,...

1) For a concave mirror at what object distance does the
associated image transition between upright and inverted?
2) As the object distance increases through the distance you
answered in part one does the image transition from upright to
inverted or from inverted to upright?
3) For object distances slightly less than the distance you
answered in part one is the image location near or far from the
mirror and is it in front of or behind the mirror?

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...

Starting with a real object, answer the following
statements (True or False) about the image formed by a single
lens?
a) A converging lens can produce a virtual,
upright, enlarged image.
b) A diverging lens can produce a real, inverted,
reduced image.
c) For a converging lens an object has to be placed
between the focal point and the lens in order to form a virtual
image.
d) A converging lens can never produce a virtual,
upright, reduced image.
e) A converging lens cannot produce...

9. For a converging lens, when is the image upright? When is the
image inverted?Can you use arbitrary rays to find the position of
the image?

An object is 7 cm in front of a converging lens with a focal
length of 10 cm .
Part A
Determine the location of the image.
Part B
Is the image upright or inverted?

An object 13 cm tall is located 37cm from a converging lens with
a focal length of 45cm. Find the location and height of the image,
and whether the image is upright or inverted, and whether it’s real
or virtual.

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...
