What is the nature of an image formed by a concave lens?
A concave lens always forms a virtual image.
What is the nature of the image formed by the concave lens when the object is placed very close to the lens?
What is the nature of the image formed? In both the cases when object is placed at infinity or between infinity and optic centre the nature of image formed is “Virtual and Erect”.
What will be nature of image formed by concave mirror when object is placed at focus?
When the object is placed between principal focus and pole of a concave mirror, an enlarged, virtual and erect image is formed behind the mirror.
What type of image will form by a concave lens when an object is placed at the focus of the lens?
In the case of a concave lens, the produced image is always – virtual, diminished and erect, for any position of the object.
What is the nature of image formed by the lens?
Concave lens form virtual and erect image on the same side of the lens between F1 and O. It is always diminished….Characteristics of images by symmetrical lens.
| Object position | Between F1 and O |
|---|---|
| Image position | On same side as object |
| Image size | Magnified |
| Nature of image | Virtual, erect |
| Application | Magnifying glass |
What is the nature of the image formed by concave and convex lens?
Summary of Image Formation by Concave and Convex Lens
| Image formation by Concave Lens | ||
|---|---|---|
| Object Location | Image Location | Image Nature |
| Infinity | At F2 | Virtual and Erect |
| Beyond Infinity and Zero | Between F1 and Optical center | Virtual and Erect |
What is the nature of the image formed by the convex lens?
Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3). Real images are always inverted, but they can be either larger or smaller than the object.
What is the nature of image formed by a concave mirror if magnification produced by mirror is 3?
virtual and erect
What is the nature of the image formed by a concave mirror if the magnification is 3. Since the value of magnification has a positive value the image formed will be virtual and erect.
Where is the image formed in convex lens?
When an object is placed at infinity, the real image is formed at the focus. The size of the image is much smaller than that of the object.
When the object is placed at the focus of concave lens the image formed is a real and smaller C virtual and smaller by virtual and inverted and real and erect?
Hence when an object is places between focus and the pole of a concave mirror,then image formed is virtual,erect and magnified image . Correct option is : virtual, erect and enlarged.
What is the difference between image formation by concave and convex lenses?
The size of the image is much smaller than that of the object. When an object is placed at a finite distance from the lens, a virtual image is formed between the pole and the focus of the convex lens. The size of the image is larger than that of the object. Summary of Image Formation by Concave and Convex Lens
What happens when an object is placed between focus and pole?
When an object is placed in between focus and pole, a virtual image is formed. The size of the image is larger than that of the object. When an object is placed at infinity, a virtual image is formed at the focus. The size of the image is much smaller than that of the object.
What is the effect of concave mirror on image?
The object and the image will be at the same place. Concave mirror converges all rays of light at the focus. In case of object placed at focus the rays of light reflected from the surface of object will be diverging in nature. These rays will be incident on the surface of concave mirror, get reflected and converge at the focus.
What happens when a ray falls on a concave lens?
Guidelines for rays falling on the concave and convex lenses When a ray strikes concave or convex lenses obliquely at its pole, it continues to follow its path. When a ray, parallel to the principal axis strikes concave or convex lenses, the reflected ray passes through a focus on the principal axis.
