What is virtual object?

  1. May 1, 2015 #1
    In the following figure AB which is behind the mirror is virtual image of object AB placed at some point between the pole and focus.

    So,is virtual object something we will get if we treat this virtual image as object i.e when we place a mirror in right side of this virtual image AB ,then the incident ray will come from AB and it's image will be formed at this second mirror.Let's name it A"B" So,the virtual image of first mirror i.e AB is virtual object for the second mirror.That's what we mean by "virtual object"right?

    But I think there is something wrong in
    Because AB is virtual image of first mirror and rays cannot diverge from or converge at virtual image.

    I can't make heads or tails of what you're trying to explain here. Why are you even introducing a 2nd mirror?

    Riddle me this. How is the ray going to get to the second mirror if it's behind the first one?

    My point is that it's important to understand the setup and how it works before you change it.

    Anyways, I found this video which I think will explain what a virtual image object is very well:



    For mirrors, you would obviously have to place the 2nd mirror in the path of the light after it bounces off of the 1st mirror, which means it must be on the left side of the diagram, not the right. Otherwise, you treat it just like you do a lens.

    But I want to understand virtual object.Let me watch the video and then I will inform I understood or not.

    I'm sorry, I meant virtual object, not image.
