Question

What is an image of an object?

Answer 1

1. When light rays coming off an object produce a copy of the object by intersecting, that is called an image of object.
2. Images can be real or virtual.
3. In real images rays physically form an image. If we put a screen in this place, we physically see the image. Example diagram is shown below.
4. In a virtual image, the rays seem to come from some other image not the real object. If we put a screen in this place, we do not physically see the image. Example diagram is shown below.
5. We see above diagram, If we put a screen behind the plane mirror in place of the virtual image, we will not see any physical image.
