Virtual Object — MirrorMediumQuestion 20200
Question
A virtual object in optics is:
- AAn object that cannot be seen
- BA point from which converging rays appear to converge (behind the mirror/lens)Correct
- CAn object placed at infinity
- DAn image acting as object after another optical element
Correct answer
A point from which converging rays appear to converge (behind the mirror/lens)
Explanation
A virtual object occurs when a converging beam (from a lens or mirror upstream) would converge behind the current optical element. The element intercepts the beam before it converges — the virtual object is where convergence would have occurred.
