Final answer:
When far away from a concave mirror and beyond the focal length, you typically see a real, inverted image. At the focal point, there is no image since the reflected light rays are parallel. However, virtual images formed by concave mirrors within the focal length can be both seen and photographed.
Step-by-step explanation:
Understanding Concave Mirror Reflection
When you stand far away from a concave mirror, the type of image you see depends on the distance you are from the mirror. If the object distance (do) is greater than the mirror's focal length (f), the image formed is a real, inverted, and possibly diminished image of yourself, depending on exact positioning. However, when the object is placed very far from a concave mirror, effectively at infinity, the image is real, inverted and very small, almost a point at the focal point of the mirror.
If the object is within the focal point of a concave mirror, that is, if the object distance is less than the mirror's focal length, the mirror will produce a virtual, upright, and magnified image, which is the case with makeup mirrors. The confusion may stem from the fact that when an object is exactly at the focal point, the image is at infinity, which makes the image disappear because the rays are parallel and never meet, giving the impression there is no image formed.
Understanding the nature of virtual images, they are formed when light rays appear to diverge from a point without actually doing so. They appear to originate from a location behind the mirror. Consequently, one can initially think that they would not be able to be photographed, but it is indeed possible because the camera captures light rays that have been reflected in a manner consistent with those coming from a real object. Thus, virtual images can be seen and photographed as they appear to our eyes.
