If we can see a virtual image, why can't we obtain it on a screen?
Sure. That's why the eye must focus a real image on the retina.Raze2dust said:but then, isn't the retina of the eye a screen?
Yes, do try it. A magnifying glass should work.Raze2dust said:ah ok..so if we keep a lens in the place of the eye then we can obtain it on a screen behind the lens right? i'll just try that out..
A virtual image is an image that appears to be in a location where light does not actually reach. In order for an image to be seen on a screen, light must be able to physically reach the screen. Since a virtual image does not have physical existence, it cannot be projected onto a screen.
A real image is an image formed by the convergence of light rays at a specific location, such as on a screen. It can be captured and seen by the human eye. A virtual image, on the other hand, is an optical illusion that appears to be in a different location than where light actually reaches. It cannot be captured or projected onto a screen.
Yes, it is possible to create a virtual image using technology such as holograms or virtual reality. These technologies use complex techniques to trick our brains into perceiving an image in a different location than where light is actually reaching. However, these images are still not physically present and cannot be projected onto a screen.
No, it is not possible to obtain a virtual image using mirrors. Mirrors can only reflect light that is physically present in the environment. They cannot create or reflect virtual images, which do not have physical existence.
Optical illusions use tricks and distortions to create the perception of a virtual image. These images are not actually present, but our brain interprets them as real due to the way our eyes and brain process visual information. However, these illusions are not the same as a virtual image that can be projected onto a screen.
