Final answer:
The image formed by a concave mirror can either be real or virtual depending on the position of the object. If the object is beyond the mirror's focal point, a real, inverted image is made. But if the object is within the focal point, a virtual, magnified, upright image is made.
Step-by-step explanation:
When an object's image is viewed in a concave mirror, the image can either be real or virtual. This depends on the object's position relative to the mirror. If the object is situated beyond the focal point of the concave mirror, a real, inverted image is formed. However, if the object is positioned within the focal point, a virtual, magnified, and upright image is produced. For example, in shaving or makeup mirrors, which are concave in nature, the user's face, when close to the mirror, appears larger or magnified, showing a virtual image.
