Virtual images
are always formed by convex mirrors and are formed by concave mirrors when the object is placed in front of F.
What is the image formed by convex mirror?
Image formed by a convex mirror is always
virtual and erect
. When an object is placed at infinity, virtual image is formed at focus and the size of the image is smaller.
What type of image is formed by a concave mirror?
Both real and virtual images
are formed by the concave mirror. When the object is placed very close to the mirror, a virtual and magnified image is formed.
What type of image is formed by concave and convex mirrors?
A concave mirror will form
a virtual or real image
. A convex mirror will only form erect and virtual images. Based on the placement of the object, virtual or real image will be formed. Convex mirror forms only virtual and erect images irrespective of the position of the object.
What type of image is formed by convex lens?
A convex lens forms
a virtual image
when the object is kept between the lens and its focus but the image formed is an enlarged one.
What type of image is formed by a convex mirror write two practical uses of convex mirror?
(a)
a virtual and erect image
is formed. #Convex mirror is used in vehicles. It is widely used as rear view mirror in automobiles and vehicles bcoz it can diverge light rays and forms virtual images. #convex mirror is used in magnifying glasses.
Why is the image formed by a convex mirror always virtual?
Convex mirrors always form virtual images because
the focal point and the centre of curvature of the convex mirror are imaginary points and that cannot be reached
. So the image is formed inside the mirror and cannot be projected on a screen.
What is convex mirror concave mirror?
Spherical mirrors contain curved surfaces which are painted on either one of the sides. When an inward surface of a spherical mirror is painted, then this type of mirror is considered a convex mirror. In the meantime, when
the outward surface of the
spherical mirror is painted, this mirror is called a concave mirror.
What happens to the image formed by the convex lens?
Image Formation by Convex Lens
In case of a convex lens, if
we bring the object close to the lens, the size of the image keeps on increasing
. As you bring the object more close to the lens, we get the image all the more enlarged.
What is convex mirror uses of convex mirror?
Two uses of convex mirror are: (i) It is
used as a rear view mirror in vehicles
. (ii) It is used as a vigilance mirror. (iii) it is used as a reflector in street lamps.
What is convex mirror for Class 7th?
Convex Mirror is a
curved mirror where the reflective surface bulges out towards the light source
. This bulging out surface reflect light outwards and are not used to focus light.
Is your image in the convex mirror a virtual image or a real image?
The image produced by a convex mirror
is always virtual
, and located behind the mirror. When the object is far away from the mirror the image is upright and located at the focal point. As the object approaches the mirror the image also approaches the mirror and grows until its height equals that of the object.
What are examples of convex mirror?
Concave mirror Convex Mirror | The examples of concave mirrors are the mirrors used in automobile head lights, reflecting telescopes, torch lights, etc. The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, etc. |

Where would the image be formed by a convex mirror if the object is placed at infinity?
Therefore, in convex mirror if the object is present at infinity then the image is formed
behind the mirror at the principal focus
, which is highly diminished, virtual and erect.
Can a convex mirror form a real image explain?
Yes
, only when the object is virtual and is placed between F and P. Fig Shows a convex mirror exposed to a converging beam which converges to a point lies between F and P. v=-xff0-x, v becomes negative(real image) only when x<f0.
What will be the nature of image formed by a convex mirror if the object is kept at infinity?
Whenever the object is kept anywhere between the infinity and the pole of a convex mirror, then we get a
diminished, virtual and erect image formed
between the pole and focus behind the mirror.
Where is convex lens used?
Convex lenses are used in
microscopes, magnifying glasses and eyeglasses
. They are also used in the cameras to create real images of objects present at a distance.
What image is formed by a concave mirror Class 7?
A concave mirror produces
a smaller, bigger and inverted image based on
its distance from the object. When the distance between object and mirror is large, a small inverted virtual image is formed. As the object is brought closer, the image becomes larger.
Where concave and convex mirrors are used?
Concave mirror is used by dentist, solar furnace, reflector of a torch, etc. Convex mirror is used in
rear view mirrors
.
What kind of image is formed by a convex mirror irrespective of the position of the object?
The image formed in a convex mirror is always
virtual and erect
, whatever be the position of the object.
What are convex mirrors?
When curved mirrors have a reflecting surface on the outside
, they are called convex mirrors. (vex stands for bulging out).
Which image represents the path of incident and reflected ray from a convex mirror when an object is placed at infinity?
Position of the object Position of the image Nature of the image | At infinity At the focus F, behind the mirror Virtual and erect | Between infinity and the pole P of the mirror Between P and F, behind the mirror Virtual and erect |

What is the size of the image formed by a convex mirror when the object is placed at infinity and the image is formed at the focus behind the mirror?
There are only two possibilities of position of object in the case of a convex mirror, i.e. object at infinity and object between infinity and pole of a convex mirror. Object at infinity: When the object is at the infinity,
a point sized image
is formed at principal focus behind the convex mirror.
Can the distance of image in convex mirror be infinity?
Reason : The distance of image in convex mirror
can never be infinity
.
