What is the figure of convex mirror?
Convex mirrors reflect light outwards (diverging light rays) and therefore they are not used to focus light. The image is virtual, erect and smaller in size than the object, but gets larger (maximum upto the size of the object) as the object comes towards the mirror. Such mirrors are also called diverging mirrors.
What is the figure of concave mirror?
A concave mirror has a reflective surface that is curved inward and away from the light source. Concave mirrors reflect light inward to one focal point. Unlike convex mirrors, the image formed by a concave mirror shows different image types depending on the distance between the object and the mirror.
What type of image is formed by a convex mirror?
virtual images
Convex mirrors always form virtual images.
What does an image look like in a convex mirror?
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.
What are the 2 cases of convex mirror?
Rules for Image Formation in a Convex Mirror
- Rule 1:
- Rule 2:
- Rule 3:
- Rule 4:
- Case 1: When object is placed at Infinity.
- Case 2: When object is placed anywhere on the principal axis.
What is the example of convex mirror?
The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, etc.
What is convex and 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 are the ray diagrams of convex mirror?
To summarise
| 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 are the 6 cases of a concave mirror?
There are six possibilities of the position of object in the case of concave mirror.
- Object at infinity.
- Object between infinity and centre of curvature (C)
- Object at centre of curvature (C)
- Object between centre of curvature (C) and Principal focus (F)
- Object at Principal Focus (F)
What are 2 examples of a convex lens?

- Microscopes.
- Projector.
- Multi-Junction Solar Cells.
What are the characteristics of a convex mirror?
Image Characteristics for Convex Mirrors. The diagram shows that as the object distance is decreased, the image distance is decreased and the image size is increased. So as an object approaches the mirror, its virtual image on the opposite side of the mirror approaches the mirror as well; and at the same time, the image is becoming larger.
Can a concave mirror produce a magnified image?
See Answer. Only a convex mirror could produce such an image. The upright images produced by concave mirrors (when object is in front of F) are magnified images. And the upright images produced by plane mirrors have the same size as the object.
What is the p’ap triangle in a convex mirror?
Based on the figure below, there are two beams of light to a convex mirror, and the convex mirror reflects the beam of light. do = object distance, di = image distance, h = P P’ = object height, h’ = Q Q’ = image height, F = the focal point of the convex mirror. The P’AP triangle is similar to the Q’AQ triangle. Therefore :
Which of the following is an example of a concave mirror?
Concave mirrors reflect light inward to one focal point. Unlike convex mirrors, the image formed by a concave mirror shows different image types depending on the distance between the object and the mirror. Give examples of concave and convex mirrors. Torch lights, automobile headlights are examples of concave mirrors.
