High School Can we get a real image of virtual objects?

[navneet9431]

Is it possible to get a real image of virtual objects, If so please explain with examples and some real life situations?

Look at my assertion "rays will not pass through virtual objects so how it can form real image", is this possible, please help.

What do you mean by "virtual objects" exactly? Every object that you can see sharply, forms a real image on your retina.

Isn't a hologram a "virtual object"?

A rainbow?

Or do you mean this?

We use the term virtual object while deriving the equation of lens. A lens has two surface. while deriving the equation. In the first part of derivation a virtual image(a image that cannot be projected on a screen) is formed by the first surface. The object of this lens surface is real.

In the second part of derivation considering the second lens surface, the virtual image of the first lens surface is taken as a Virtual object for second surface and we solve the derivation. This virtual object create a real image which we can see. We cannotdirectly observe the virtual object

Yes. Look in a mirror. What you see is a real image formed on your retina of a virtual object in the mirror

I'm not sure that's true for all holograms. I believe there are projection holograms where the light forms a real image which appears three dimensional and where the light passes through the location of the image. I would class that as a real image. But here we are again worrying about what to call something instead of discussing how something works.

I was being facetious. Often time, people do not know what they mean by "virtual object". In a hologram, the object itself is not that, merely a "replay" of the image that has been imprinted.

Both Dale and anorlunda have replied to the issue of virtual image in the "optics" sense.

Here's an example. The incoming rays from the left converge towards a virtual object at the right of the lens, but never actually pass through it, except for the single ray through the center of the lens. After refraction, the outgoing rays converge towards a real image and actually pass through it.
