Difference between real and virtual objects? (optics)

[Ravik Rocha]

I do know the difference between real and virtual images. I would like to know the difference between real and virtual objects. I need some examples.
See this picture

Hi and welcome to PF.
From the picture it seems that their definition involves whether or not real rays of light actually pass through the object or image. A virtual object or image is just a way of describing what's happening to the light because neither can have any effect in itself. A real object actually has light coming from it and a real image actually has light actually passing through it. This is why people say that you can't project a virtual image.
A word of caution about this common worry about naming things. The terms real and virtual in this respect are only crude classifications, beloved of old fashioned ,rote teaching and don't have a lot to do with understanding how to predict how an actual optical system will perform. I can't imagine any worth while test or exam would demand that you use the 'correct' term. More important would be to predict where the image is formed.
A 'virtual Object' will have been formed by another optical element further up the chain which will have formed a virtual Image (the same virtual thing with two different names)

If you put an optical instrument on the road of the light rays to create a real image, the real image that will become virtual objects. You know how to a real object create a real image?

I would like to know the difference between real and virtual objects. I need some examples.

Consider, for example, the Galilean telescope which contains two lenses. Its objective lens has a real object. Its eyepiece, which is a concave lens, has a virtual object.

A real object is one which is practically present in front of an Optical Instrument.

A virtual object is an an image produced by an optical instrument which is made incident on any other optical instrument.

Suppose you have two mirrors. You place an object in front of one mirror. The mirror will produce an image and this image can be made incident on the other mirror. For the other mirror, thus image is virtual object.

Are you sure about that? A real object also means the incident light is a divergent beam, and a virtual object means the incident light is a convergent beam. The first mirror does not transform a divergent beam into a convergent one.
