Doubt & Answer Explanation

Answer Explanation

Let us look at all the options one by one. I am assuming that you are talking about a concave mirror.
If the incident rays are converging, we have a real image.


All incident rays converge except when the incident rays are coming from an object placed at infinity. Therefore, it is NOT necessary that when incident rays converge, we have a real image. We can have a virtual image also when the object is placed between F and P.

If the final rays are converging, we have a real image



This option is correct. When the final rays converge, clearly a real image is formed as this is the definition of a real image.


The image of a virtual object is also virtual



A virtual object is simply the image of a real object through another mirror or lens.  So when the image formed after refraction or reflection once is made the object for another reflection, then the object is virtual for the second reflection.


The image of a virtual object may or may not be virtual depending on whether the rays coming from the virtual object meet in reality or not. So this option is wrong as it is NOT necessary that the image of a virtual object should necessarily be virtual.

If the image is virtual, the object is virtual.



This statement is clearly wrong. If the image is virtual, that simply means that the final rays do not meet in reality. Where those rays are coming from is something we don't know about. They may be coming from a real object or a virtual object.
