Final answer:
When the crossover mirrors are adjusted, you can see multiple images of an object placed between the mirrors, with the closest image being the virtual image.
Step-by-step explanation:
When the crossover mirrors are adjusted, you should be able to see multiple images of an object placed between the mirrors. These images are formed by the reflection of light between the mirrors. The number of images formed depends on the angle at which the mirrors are adjusted and the position of the object.
The closest object you can see clearly will be the virtual image formed by the reflections in the crossover mirrors. This image will appear to be at the same distance as the actual object, but it will be inverted.
For example, if you place an object 5 meters away from the crossover mirrors and adjust the mirrors at a specific angle, you may see multiple images of the object at different distances from the mirrors. The closest image to the mirrors will be the virtual image, and it will appear to be at a distance of 5 meters.
