Real Image of Virtual Object

Question:

In the case of concave mirror, if u less than f, virtual image i1 is formed. If second concave mirror is added, which the distance between its principle and i1 greater than 2f, can image i2 be captured on a screen? i.e. is there any situation that real image formed from virtual object?

Answer:

If I understand your question correctly I think the answer is yes. To the second mirror, the source of light rays to form i2 could either be from a real object, or the real or virtual image of a real object.
