Why are infinite images not seen when two plane mirrors are facing each other?

Question

Short/Brief Note

Solution

Infinite images are not seen when two plane mirrors are facing each other because:

After every successive reflection, some amount of light energy is absorbed. Thus luminosity of the image goes on decreasing, till they are no longer visible.
As the distance of images from the eye goes on increasing, it is unable to resolve far off images.
