What is the image of 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 diagram of concave and convex mirror?
What Is the Difference Between a Concave and Convex Mirror?
| Concave Mirror | Convex Mirror |
|---|---|
| Based on the object’s placement, an image formed by the concave mirror is virtual or real. | The image formed by the convex mirror is only a virtual and erect image irrespective of the object’s position. |
What type of image is formed by the concave?
Concave lens always form virtual, erect and diminished image.
What is the image in a convex mirror?
The image formed in a convex mirror is always virtual and erect, whatever be the position of the object.
How do you draw a concave ray diagram?
Step-by-Step Method for Drawing Ray Diagrams
- Pick a point on the top of the object and draw two incident rays traveling towards the mirror.
- Once these incident rays strike the mirror, reflect them according to the two rules of reflection for concave mirrors.
- Mark the image of the top of the object.
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)
Which image is formed in convex mirror?
The image formed by the convex mirror is laterally inverted.
How is an image formed by a concave lens?
Image Formation in Concave Lens An object placed at a finite distance from the lens forms a virtual image between the pole and the focus of the convex lens. As a result, the size of the image is smaller than that of the object.
What is the position of image in concave lens?
(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 diagram of convex?
To summarise
| Position of the object | Position of the image | Size of the image |
|---|---|---|
| At infinity | At the focus F, behind the mirror | Highly diminished, point-sized |
| Between infinity and the pole P of the mirror | Between P and F, behind the mirror | Diminished |
