Final answer:
The image formed when an object is placed between the focal point and the vertex of a concave mirror is enlarged, inverted, and virtual, appearing to be behind the mirror.
Step-by-step explanation:
For an object placed between the focal point (F) and the vertex (V) of a concave mirror, the types of images that can be formed are specific. From the options given, the correct assessment is that the image will be enlarged, inverted, and it will form behind the mirror, making it a virtual image.
Since the object is within the focal point of the concave mirror, the rays after reflection diverge. However, if these divergent rays are extended backwards, they appear to come from a point behind the mirror, thus creating a virtual image. This virtual image is also enlarged and remains upright, as opposed to being inverted, which is characteristic of real images formed by concave mirrors when the object is placed beyond the focal point.
