In case of a concave lens the only possibility is that when parallel rays make an entry then they have to diverge. NO diverging rays can form a real image on a screen as they could not meet at a point. If the already diverging rays make an entry then they get diverged further and so no chance of getting real image. Hence the diverging rays appear to originate from a point on the same side of the object and so a virtual image.
In case of a convex lens if the object is placed in between the optic centre and the focal plane then the refracting rays have to diverge and so virtual image.
This is what a palmist does as he uses to see the lines on the palm to foretell the future.
What else can I help you with?
What do you call an image created in a mirror?
Its called a virtual image.
Is the image you see in a plane mirror a real image or a virtual image?
virtual :-)
What is the orientation of a virtual image?
A virtual image is always upright in relation to the object.
Why is negative sign associated with virtual image?
A negative sign is associated with a virtual image because the light rays do not actually converge at the location of the virtual image. Instead, they appear to diverge from a point behind the mirror or lens, creating the virtual image. Mathematically, this distance is represented as negative to indicate the direction of the virtual image.
Is using a plane mirror to form virtual image one of its uses?
A plane mirror forms a virtual image. If it's reflected, then the light does not come from the image, and it is virtual.
What type of image a mirage is?
a virtual image
What type of lens form a virtual image?
A convex lense forms only a virtual image.
How can a real image be distinguished from a virtual image and can each type of image be projected on screen?
If an image can be formed on screen it is classified as real. Virtual images cannot be projected on an image.
Does a flat mirror produce a real or virtual image?
virtual image ( not on screen, brain interpreting)
Does a diverging lens create a virtual image or a real image?
it will always create a virtual image because when you extend its light rays, they diverge and never end up intersecting. But if you extend these light ray backwards, they intersect to create a upright image which will always be virtual
Do cameras have a real or virtual image?
They have a real image.
What do you call an image created by a mirror?
Virtual Image
