What type image is formed?
(a) The type of image formed in a plane mirror is virtual. The virtual images form when the light rays appear to meet at a definite point, after reflection. (b) The type of image formed on a cinema screen is real. The real images form when the light rays meet at a particular point after reflection.
What are the two types of image formed?
| Real image | Virtual image |
|---|---|
| The rays of light after reflection meet at a point. | The rays of light after reflection appear to meet at a point. |
| It is always inverted. | It is always erect but laterally inverted. |
| It is formed on the same side of the mirror as the object. | It is always formed on the back side of the mirror. |
What type of image is formed in concave?
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.

| S No. | Position of Object | Nature of Image |
|---|---|---|
| 1. | At infinity | Real and inverted |
| 2. | Beyond the centre of curvature C | Real and inverted |
| 3. | At the centre of curvature C | Real and inverted |
| 4. | Between C and F | Real and inverted |
Which image is formed in convex mirror?
virtual and erect
The image formed in a convex mirror is always virtual and erect, whatever be the position of the object.
How many types of image are formed?
Answer: 3 type of images.
Which type of image is formed by convex mirror?
What image is formed in convex mirror?
What image is formed on the retina of the eye?
real and inverted
The image formed on the retina is real and inverted. The retina comprises specialized cells that are sensitive to light, known as rod and cone cells. These cells get stimulated and send signals to the brain which turns them into erect images that allow us to see. So, the correct answer is ‘real and inverted’.
How are three types of images formed by mirrors?
The three types of images formed by mirrors (cases 1, 2, and 3) are exactly analogous to those formed by lenses, as summarized in the table at the end of Image Formation by Lenses. It is easiest to concentrate on only three types of images—then remember that concave mirrors act like convex lenses, whereas convex mirrors act like concave lenses.
What kind of images are formed by lenses?
As you bring the object more close to the lens, we get the image all the more enlarged. So here we can say that the images formed can be of a variety of types. We can have diminished inverted image, small sizes inverted image, enlarged inverted image, enlarged erect image.
Why is the formation of an image important?
The image that is formed is inverted. This image is then interpreted by the brain and that makes us able to understand things. Due to angle formation , we are able to perceive the height and depth of the object we are seeing.
How is an image formed in the eye?
When light falls upon the particular object , it is reflected back after striking through the object. The rays of light when passed through the lens of eye , form a particular angle , and the image is formed on the retina which is the back side of the wall.
