When the object is located at a location beyond the 2F point, the image will always be located
somewhere in between the 2F point and the focal point (F) on the other side of the lens
.
What is the position of image when an object is placed beyond 2F of a convex lens?
When an object is placed beyond 2f in front of a convex lens, then the image formed is
between f and 2f on the other side of the lens
, it is real, inverted and smaller than the object.
When object is beyond 2F in front of concave lens the image formed?
The two refracted light rays meet each other at point A’, between the focus F and centre of curvature 2F on the other side of the lens. In this way,
a diminished, real and inverted image A’B’
is formed.
Where will the image form if the object is placed between F and 2F?
Complete answer:
From the above ray diagram we can observe that If we place the object between F(focus)and 2F the
image formed is always beyond 2F
. The images are real and always inverted.
Where will image be formed when the object is kept in beyond 2F 1 explain?
| Position of the object Position of the image Relative size of the image | At 2F 1 At 2F 2 Same Size | Between F 1 and 2F 1 Beyond 2F 2 Enlarged | At focus F 1 At infinity Infinitely large or highly enlarged | Between focus F 1 and optical Center O On the same side of the lens as the object Enlarged |
|---|
When object is placed at 2F?
When an object is placed at twice the focal length i.e.,2F image is also formed at 2F on the other side of the length. The
image formed is inverted
as it looks upside down as that of an object and it can be caught on the screen, so it is a real image.
What is the position of the image if the object is placed beyond the Centre of curvature on the principal axis of convex lens?
| S No. Position of Object Position of Image | 1. At infinity At the focus | 2. Beyond 2F Between the focus and centre of curvature | 3. At 2F At the centre of curvature | 4. Between F and 2F Beyond the centre of curvature |

What is 2F in convex lens?
For a converging lens, parallel light rays will converge to a point. This is the focal point (F) of the converging lens.
A point that is twice the distance from the lens as the
focal point is labeled 2F.
Which are the correct characteristics of an image when object is between 2F and F in a convex lens?
If the object is placed between 2F and F, the image will appear beyond 2F on the other side. The
image will be real, inverted, and enlarged
. For convex lenses, when the object is placed inside F, the image will be on the same side of the lens as the object and it will be virtual, upright, and enlarged.
When the object is placed at F of concave lens then the formation of image is?
| Position of the object Position of the image Nature of the image | At infinity At focus F 1 Virtual and erect | Between infinity and optical centre O of the lens Between focus F 1 and optical centre O Virtual and erect |
|---|
What happens when the object is placed at F?
Sample Response: The image created by the object is located on 2F behind the lens, real, inverted, and the same size as the actual object. What happens when the object is placed at F? … Sample Response:
No image will be formed because the rays will not converge to or diverge from a common point
.
When the position of object lies between F1 and 2F1 the image formed is beyond 2F2 what will be the nature of image formed?
| Image formation by Convex Lens | Object location Image location Image nature | Beyond 2 F1 Between 2F2 and F2 Real and Inverted | Between 2F1 and F1 Beyond 2F2 Real and Inverted | At F1 At infinity Real and Inverted |

What is 2F in concave mirror?
For a concave mirror, when object is at 2f. image is formed at 2f. Hence,
v1=−2f
for concave mirror. Image formed by concave mirror serves as an object to plane mirror. Position of plane mirror with respect to concave mirror is d=−f.
At which location of object in front of concave lens the image between focus and optical center is formed a anywhere between center and infinity B at F C at 2F D infinity?
(a) In the case of a concave lens, when an object is placed anywhere between the optical centre and infinity, then the position of the image is between the optical centre and the focus, nature of the image is virtual and erect and size is diminished.
What is the position of image when object is placed at 2F 1?
Answer: When an object is placed at 2F1 the
image is formed at 2F2 and the image formed is real, inverted and of same size as that of object
.
When an object is placed beyond the center of curvature?
In fact, it can be generalized that anytime the object is located beyond the center of curvature, the image will be located somewhere between the center of curvature and the focal point. In such cases, the
image will be inverted and reduced in size
(i.e., smaller than the object).
What is the location of image in convex lens between F and lens?
| Object location Image location Image nature | Infinity At F 2 Real and Inverted | Beyond 2F 1 Between 2F 2 and F 2 Real and Inverted | Between 2F 1 and F 1 Beyond 2F 2 Real and Inverted | At F 1 At infinity Real and Inverted |
|---|
When an object is placed between F and optical center in front of a concave lens the image formed is virtual and erect?
When an object is placed between the focus (F) and optical centre (O) of convex lens, then the image is formed
beyond F1
to the same side of as that of object and is erect, virtual and magnified image.
How do you find the image distance of a converging lens?
- To calculate the image distance, the lens formula can be used.
- 1/u+1/v=1/f.
- where.
- u is the object distance.
- v is the image distance.
- f is the focal length of the lens.
- If you know the focal length and object distance, using the above formula image distance can be calculated.
When object is at infinity where is image formed?
If the object is at the infinity, the image is formed
at the focus
. If the object is at the focus, the image is formed at the infinity. And the spherical mirrors produce virtual images only when the image is formed behind the mirror.
When an object is placed in front of the concave mirror at a point between F and C 2F the image is?
The Object is Placed Between C and F
Here the two rays considered are
one parallel to the principal axis
and other passing through the principal focus of the concave mirror. The image is formed beyond C. The image is larger compared to the size of the object and it is real and inverted.
Where will the image be formed if the object is placed at focus of a concave mirror?
If an object is placed at the focus of a concave mirror, where is the image formed? If an object is placed at the focus of a concave mirror, the
image is formed at infinity
.
What is R 2f in physics?
R is the
radius of curvature
and f is the focal length of a spherical mirror. … For spherical mirrors of small apertures, the radius of curvature is found to be equal to twice the focal length, i.e., R = 2f. This implies that the principal focus of a spherical mirror lies between the pole and the centre of curvature.
How do you prove R 2f in a convex mirror?
The normal to the surface at point B is CB and CP = CB = R, is the radius of curvature. The ray AB, after reflection from mirror will pass through F (concave mirror) or will appear to diverge from F (convex mirror) and obeys law of reflection, i.e., i = r.
Is the center of curvature 2f?
| SIGN + – | m – magnification Upright image Inverted image |
|---|
When object is placed at F of convex lens the nature of image is?
| Object Position Image Position Image Characteristics | At F At infinity Infinitely big | Moving from F toward lens Moving from -infinity toward lens Decreasing in size, virtual, upright, larger than the object |
|---|
Where an image is formed by the concave lens when the position of the object between infinity and optical centers?
EXPLANATION: When the object is between the infinity and optical center of the lens then the image forms
between focus and optical center
which is diminished, virtual and erect. So option 1 is correct.
Where will be the image formed by a concave lens if the object is kept between optic center and infinity of the lens?
A diminished, virtual and erect image is formed between
principal focus F1 and optical centre
, O; when object is placed between optical centre and infinity of a concave lens.
What is F1 and F2 in convex lens?
However a convex lens has two spherical surfaces and hence it has two principal foci or two focal points which are usually denoted by the letters ‘F1’ and ‘F2’ and are known as the first principal focus (F1) and
the second principal focus (F2)
. …
What is the location of an object in front of a concave lens?
A concave mirror and a converging lens will only produce an upright image if the object is located in
front of the focal point
. 4.
