The fact is that virtual images are the only ones we see directly with the eye. It is very difficult to see a full real image, you can only see parts of it. A virtual image is one where the light rays appear to come from a points in space. The eye can't tell the difference between light rays that come from a point on a real object, and light rays that approach the eye in the exact same angles as ones from that point on a object.
I can take an object you are looking at, remove it but replace it with light sources that duplicate the angles that points on that object produce light, and you could not see the difference. The reason is that the only way we see the object is from the light coming from it and if we can "simulate" that light we will make that object appear real to the eye.
The same happens with real images, because the light from a real image also replicates the angles of the light from an object, but the light is limited lo a small range because of the lens aperture, so we can only see parts of the image (the light cones defining a real image are narrow and limited by the lens aperture).
NOTE: a screen makes a real image visible by scattering the light from the image so that it can be seen from a wide range of angles.
What else can I help you with?
Do cameras have a real or virtual image?
They have a real image.
Is true of a real image?
a real image can be projected
Does convex lens produce real image?
No, convex lens does not produce a real image. It reflects the real image
Can plane and convex mirrors produce real image?
no it does not produce real image . it produce virtual and erect 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.
What is an image which can be projected onto a screen is called?
It is called a real image. Only a real image can be projected onto a screen.
What type of mirror can create a real image?
A concave mirror can create a real image.
Which lens does not form a real image?
concave lens does not form a rel image and convex MIRROR does not form a real image
How and when is the image inverted?
Whenever a real image is formed by a real object,the image is always inverted. for eg when light rays from infinity falls on convex lens it forms a real and inverted image at focal plane.
Is it plain mirror or concave mirror producing magnified real image?
A plane (flat) mirror reflects an image which is the same size and shape, and colour as the object in front of the mirror. A concave mirror can produce a magnified image. If the image is in front of the mirror it is a real image; if behind it is a virtual (non-real) image. A real image can be cast upon a white the best) surface
Is the image you see in a plane mirror a real image or a virtual image?
virtual :-)
Can a real image be seen if you place a screen where the image is focused?
Yes. That's a good quick way to determine whether or not a real image exists. You can also use a piece of thin tissue paper, kleenex, or toilet paper, and see the image from the other side. Put a piece of photosensitive material there at the real image, and you get a permanent photo.
