When you keep an object in front of a concave mirror, an enlarged image of the object is formed when it is kept close to the mirror and an inverted image of the object is formed when it is kept at a distance. A convex mirror always forms a small and an erected image of the object.
Can a convex mirror ever form a real image?
No, only a virtual image. You need an additional convex lens in order to turn it into a real image. See: LeeH (published on 12/10/2009)
Why can convex mirrors form only one type of image?
“Why do plane mirrors and convex mirrors form only virtual images?” Because the image is not formed at the surface of the mirror. You can’t trace light rays back to the surface of a mirror to find the origin of the image. The focal point of such images is somewhere other than the surface of the mirror. That’s what “virtual” means in this context.
Does a convex mirror form a virtual or real image?
convex mirrors can produce real images as well. If the object is virtual, i.e., if the light rays converging at a point behind a plane mirror (or a convex mirror) are reflected to a point on a screen placed in front of the mirror, then a real image will be formed. What size of image does a convex mirror produce?
What type of image can a convex mirror produce?
Convex mirrors always form virtual images. This is 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 nature of image formed by convex mirror?
The image formed by a convex mirror is virtual, erect and diminished.
What is nature of image formed by concave mirror?
Concave mirrors form both real and virtual images. When the concave mirror is placed very close to the object, a virtual and magnified image is obtained and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed.
What is the nature of the concave image?
Detailed Solution. The correct answer is Real and inverted. The image formed by the concave mirror when the object is placed beyond the center of curvature is Real and Inverted.
What is the nature of image formed by convex lens?
The image will be virtual and erect since the magnification has a positive value.
What is the image formed by convex lens?
Image formed by a convex lens is inverted. Double convex lenses have focal points on both sides of the lens, but it is also necessary to use points at twice the focal length to locate objects and images.
Which type of image is always formed by a convex mirror?
virtualThe image formed by a convex mirror is always erect, virtual and diminished irrespective of the position of the object. Whereas a concave mirror can form both real and virtual images depending upon the position of the object with respect to the mirror.
Can convex mirror form real image?
Assertion : Plane and convex mirrors can produce real images of objects. Reason : A plane or convex mirror can produce a real image, if the object is virtual.
What are the differences between concave mirror and convex mirror?
Basically, the reflecting surface of the convex mirror bulges outside while the concave mirror bulges inwards. The major difference is the image that forms in these two mirrors. In other words, diminished images form in convex mirrors while enlarged images form in concave mirrors.
What is the nature of the focus of a concave?
A concave lens have a virtual focus because the rays diverges outside and seems to meet virtually at focus.
What is the nature of concave and convex lens?
Convex lenses are also known as converging lenses since the rays converge after falling on the convex lens. The concave lenses are known as diverging lenses, as the rays diverge after falling on the concave lens.
What is the image of a concave lens?
Concave lenses create only virtual images. After the rays are refracted, they never converge and so there will be no real images. All concave lens images will be upright, virtual, and diminished, and can be found between the F and the lens.
What is the nature of the image?
Definition : Definition : Incident rays starting from a point object, and reflected from a mirror, either actually meet at or appear to come from a point. The other point is called the image of the point object.
What is the nature of an image formed by a concave mirror?
The nature of this image formed by concave mirror is real and inverted.
What is the reflective surface of a convex mirror?
The reflective surface in convex mirror is on the bulge or outer side. Whatever be the distance between the mirror and the object, the image formed by a convex mirror is always diminished, erect and virtual. Convex mirrors reflect the light incident on them and therefore convex mirrors are also known as diverging mirrors.
What is the same size image formed at the center of curvature?
The nature of this image formed by concave mirror is real and inverted.
Why is a convex mirror called a diverging mirror?
The light gets diverged from the reflecting surface of a con vex mirror which is why it is also known as a diverging mirror.The images formed by the convex mirrors are always erect, virtual, and diminished regardless of the distance between the mirror and the object.
What is the nature of a diminished image?
The nature of this image formed by concave mirror is real and inverted.
What is a plane mirror?
Plane Mirror: A mirror that has a flat or plane reflective surface. 2. Spherical Mirror: Mirrors that have curved reflecting surfaces are known as spherical mirrors. A Spherical mirror is formed when you cut out a piece from a sphere and make either of the surfaces reflective.
What is the midpoint of a spherical mirror?
Understanding ray diagrams will become easier if you learn more about terms used in ray diagram and image formed by concave and convex mirror. 1. Pole: It is the midpoint of a spherical mirror. It is represented by the letter ‘P’. 2.
What is the distance from the reflection surface to the focal point?
The distance from the reflecting surface to the focal point is termed the mirror's focal length. The size of the image depends upon the distance of the object from the mirror and it's position with respect to the mirror's surface.
Which side of the mirror is the light ray reflected from?
Light rays parallel to the optical or principal axis are reflected from the surface in a manner that diverges from a focal point that is behind the mirror. Images formed with convex mirrors are always right side up and reduced in size.
Where is the soldier placed in the mirror?
In this case, the soldier is placed at the center of curvature and the reflected image is upside down and in front of the mirror's center of curvature. The convex mirror on the right-hand side of figure, however, has a reflecting surface that curves outward, which resembles a portion of the exterior of a sphere.
Answer
concave mirror may be virtual or real , diminished or enlarged, erect or inverted images

Why do light rays converge in a concave mirror?
The light rays converge in a concave mirror because the normal on the surface of the mirror is not the same at all points of the mirror and changes due to the curve of the mirror. Same reasoning is valid in the case of convex mirrors which diverge the incident light rays.
What are the two types of spherical mirrors?
The two types of spherical mirror commonly used are concave mirror and convex mirror . They are made by polishing the inner or outer side of a curved glass. Convex mirror is made by polishing the outer curved surface while a concave mirror is made by polishing the inner curved surface.
