Question

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, inverted, reduced image.

Please do not copy paste answer from somewher eelse, I already tried understanding that way and answeres were wrong.

Answer #1

a) False, an object placed further than foacl length away from the lens will be a real, inverted, and reduced image.

b) True

c) False, an object placed further than 2f away from the lens will be a real, inverted, and reduced image.

d) True, the virtual, upright images it forms are always magnified

e) False, an object placed further than 2f away from the lens will be a real, inverted, and reduced image.

f) False, This is also false as diverging lens cannot produce a real image.

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...

1A)
A real image has the following characteristics:
(I) it cannot be formed by a diverging lens
(II) it is always inverted
(III) it can be formed only if the object is very far away
(IV) it must be on the same side of the lens as the object
The correct answers are
III and IV
I and IV
II and IV
I and II
1B)
A lens produces a diminished image. So
(I) the lens can be diverging
(II)...

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

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?

The lateral magnification of an object by a lens is negative.
Which is true?
The image must be a virtual image.
The image could be either a real or virtual image.
The image must be a real image.
The lateral magnification of an object by a lens is positive.
Which is true?
The image could be either a real or virtual image.
The image must be a virtual image.
The image must be a real image.
Which is true about...

A diverging lens with a focal length of -15 cm and a converging
lens with a focal length of 15 cm have a common central axis. Their
separation is 12 cm. An object of height 1.0 cm is 10 cm in front
of the diverging lens, on the common central axis.
(a) Where does the lens combination produce the final image of
the object (the one produced by the second, converging lens)?
in cm
(b) What is the height of...

An object which is 1.23 cm high is placed 10.00 cm to the left
of a lens. It is not known if the lens is converging or diverging.
An image forms 3.20 cm to the left of the lens. (a) Determine if
the lens is converging or diverging by calculating the focal length
of the lens. (b) Calculate the height of the image. (c) Describe
the image. Is it real or virtual, upright or inverted and enlarged
or diminished?

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 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...
